An equation is shown.
30+12=x(5+2)
What’s factor (x) is missing from the equation
Answer: x = 6
Step-by-step explanation:
30 + 12 = x (5 + 2)
x (5 + 2) = 30 + 12
x (7) = 42
7x = 42
Divide both sides by 7
x = 6
Answer:
30+12=x(5+2)
or,42=7x
or,x=42÷7
So,x= 6

Step-by-step explanation:
In triangle ABC AB is equals to AB and Angle B equal to 80 find the angle A
Answer:
∠A = 20°
Step-by-step explanation:
Given:
Line AB equal to line AC
So, we can say that;
∠B = ∠C
So
∠B = ∠C = 80°
Using angle sum rule
∠A + ∠B + ∠C = 180°
∠A + 80° + 80° = 180°
∠A = 20°

How to find x (similar triangles)
Answer:
x = 2
Step-by-step explanation:
Parallel lines divides the transversals in proportion.
Therefore,
[tex] \frac{9}{4} = \frac{13.5}{x + 4} \\ \\ 9(x + 4) = 13.5 \times 4 \\ \\ 9(x + 4) = 54 \\ \\ x + 4 = \frac{54}{9} \\ \\ x + 4 = 6 \\ \\ x = 6 - 4 \\ \\ x = 2[/tex]

Answer:
[tex]x = \frac{ \sqrt{6} }{2} [/tex]
[tex]y = \frac{3 \sqrt{2} }{2} [/tex]
Step-by-step explanation:
[tex] \sin(theta) = \frac{opposite}{hypotenuse} [/tex]
[tex] \cos(theta) = \frac{adjacent}{hypotenuse} [/tex]
[tex] \tan(theta) = \frac{opposite}{adjacent} [/tex]
theta = 30°
hypotenuse = √6
opposite = x
adjacent = y
1) find x using the sin formula[tex] \sin(theta) = \frac{opposite}{hypotenuse} [/tex]
[tex] \sin(30) = \frac{x}{ \sqrt{6} } [/tex]
[tex] \sin(30) \times \sqrt{6} = x[/tex]
[tex] \frac{ \sqrt{6} }{2} = x[/tex]
[tex]x = \frac{ \sqrt{6} }{2} [/tex]
2) find y using the cos formula[tex] \cos(theta) = \frac{adjacent}{hypotenuse} [/tex]
[tex] \cos(30) = \frac{y}{ \sqrt{6} } [/tex]
[tex] \cos(30) \times \sqrt{6} = y[/tex]
[tex] \frac{3 \sqrt{2} }{2} = y[/tex]
[tex]y = \frac{3 \sqrt{2} }{2} [/tex]
Given right triangle ABC with altitude BD drawn to hypotenuse AC. If BC = 14
and DC 4, what is the length of AC? (Note: the figure is not drawn to scale.)
Answer:
49
Step-by-step explanation:
∠BAD = ∠DBC (90-∠ABD)
∠C = ∠C
ΔABC similar to ΔBDC
AC/BC = BC/AC
x/14 = 14/4
x = 14*14/4 = 49

what does 11+(r+3) equal to?
Well, if we use the Associative Property, we can switch around the positions of the 11, which is out of the parentheses. So, what we do is we put 11 and 3 into parentheses and r out of the parentheses, which makes:
r + (11 + 3)
So, now we solve the parentheses:
r + (14)
And finally, remove the parentheses. So, therefore, the answer is r + 14.

Answer:
in a triangle there is only two sides that are the same length.
Answer:
Thus the answer is A. 10 cm, 6 cm, 4 cm
Step-by-step explanation:
Triangle Inequality Theorem
Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:
x + y > z
x + z > y
y + z > x
Combining the above inequalities, and provided y>z, the third size must satisfy:
y - z < x < y + z
The first combination y=6 cm z=4 cm produces the condition:
6 - 4 < x < 10
2 < x < 10
The third side is x=10 cm and it does not satisfy the inequality.
The rest of the combinations produce true inequalities:
B. 1 < x < 15 and x=9 satisfies the conditions
C. 1 < x < 9 and x=8 satisfies the conditions
D. 6 < x < 14 and x=10 satisfies the conditions
Thus the answer is A. 10 cm, 6 cm, 4 cm

Answer:
y = (7/9)x
Step-by-step explanation:
The equation of a straight line is given as y = mx + b, where y and x are variables, m is the rate of change = change in y / change in x, while b is the y intercept (value of y when x = 0).
When no pint is used, there is no frozen yoghurt. But from 9 pints, 7 large servings of frozen yogurt is made. Let x represent the number of pints and the y represent the number of servings.
Hence, using y = mx + b, we get b = 0, because at 0 pint there is no servings. The equation be comes y = mx
m = change in y / change in x = 7 servings / 9 pints
m = 7/9
The equation is:
y = (7/9)x

(0,1) (3,-8) linear equation
Answer:
The answer is
[tex]y = - 3x + 1[/tex]
Step-by-step explanation:
❃Incase you forgot what the linear equation formula is ☟
[tex]y = mx + b[/tex]
❃Incase you also forgot, The is what the slope formula is ☟
[tex]m = \frac{y_2 - y_1 }{x_2 - x_1} [/tex]
➊ First: We are going to be solving for the slope.
[tex]m = \frac{ - 8 - 1}{3 - 0} = \frac{ - 9}{ \: \: \: 3} = - 3[/tex]
➋Second: We find the y-intercept.
[tex]y = mx + b \\ - 8 = - 3(3) + b \\ - 8 = - 9 + b \\ \frac{ + 9 = + 9 \: \: \: \: \: }{1 = b} [/tex]
➌Third: Plug in.
[tex]y = - 3x + 1[/tex]

9514 1404 393
Answer:
A'(-6, 12), B'(12, -3), C'(-3, -6)
Step-by-step explanation:
When the center of dilation is not specified, it is presumed to be the origin (0, 0). When that is the case, dilation multiplies every coordinate value by the dilation factor. For example, the x-coordinate of A is -2. The dilation factor is 3, so the x-coordinate of A' is 3(-2) = -6, as shown in your figure.
The same applies to all of the coordinates. (We assume you know how to multiply by 3.)
On the graph, each point moves to 3 times the original distance from the origin, in accordance with the new coordinates. The result is shown in the attachment.

Answer:
A = 31.68°
B = 109.45°
C = 38.92°
Step-by-step explanation:
Law of cosine: cosA = (b²+c²-a²) / 2bc
a = x = 10 b = 18 c = 12
cosA = (18² + 12² - 10²) / 2*18*12 = 368/432 = 0.851
A = 31.68
cosB = (10² + 12² - 18²) / 2*10*12 = -80/240 = -1/3 = -0.333
B = 109.45
cosC = (10² + 18² - 12²) / 2*10*18 = 280/360 = 0.778
C = 38.92
check: A+B+C = 31.68 + 109.45 + 38.92 =180.05 ≈ 80°
Wish this help!!
