x and y
are supplementary angles. y
measures 142.
What is the measure of x?
Answer:
38°
Step-by-step explanation:
y = 142°
x + y = 180°{ being supplementary angles }
x + 142° = 180°
x = 180° - 142°
x = 38°

(5x + 5)'. Find
9514 1404 393
Answer:
∠S = 38°
Step-by-step explanation:
The sum of angles in a triangle is 180°, so you have ...
(x+17)° +(2x-2)° +(5x+5)° = 180°
8x +20 = 180 . . . . . divide by °, collect terms
8x = 160 . . . . subtract 20
x = 20 . . . . . . divide by 8
∠S = (2x -2)° = (2·20 -2)°
∠S = 38°

Answer:
angle abc=125°
.......................
Answer:
125
Step-by-step explanation:
Using the angle addition postulate,
Parts of an Angle add up to form a new angle with the measure of that angle is the sum of the two separate angles.
Add ABD and DBC
[tex]65 + 60 = 125[/tex]

What is the length of arc S shown below? Enter an exact expression. The angle in the figure is a central angle in radians.
Answer:
The arc length S = 11.304 cm
Step-by-step explanation:
Explanation:-
Given that the radius of the circle 'r' = 6 cm
Given that the central angle = [tex]\frac{3\pi }{5}[/tex]
The Arc length is defined by
S = r θ
S = 6 × [tex]\frac{3\pi }{5}[/tex]
[tex]S = \frac{18\pi }{5}[/tex]
[tex]S = \frac{18(3.14) }{5}[/tex] (∵ π = 3.14)
S = 11.304 cm
The arc length S = 11.304 cm
Answer:
18pi/5

Write an equation in slope-intercept form for the line between (2,7) and (6, 19)
Answer:
y= 3x +1
Step-by-step explanation:
Slope-intercept form:
y= mx +c, where m is the slope and c is the y-intercept.
Gradient= [tex] \frac{y1 - y2}{x1 - x2} [/tex]
☆ (x1, y1) is the 1st coordinate and (x2, y2) is the 2nd coordinate
Using the formula above, slope of line
[tex] = \frac{19 - 7}{6 - 2} \\ = \frac{12}{4} \\ = 3[/tex]
Subst. m=3 into the equation:
y= 3x +c
To find the value of c, substitute a pair of coordinates.
When x= 2, y= 7,
7= 3(2) +c
7= 6 +c
c= 7 -6
c= 1
Thus, the equation of the line is y= 3x +1.

To multiply 4 x 5 3/8, the mixed number can be broken down into a whole number and a fraction. In this case, that whole number would be ____ and the fraction would be ___ eighths. Each of these parts are then ___ ___. Pls tell me the answer pls!
Answer:
Step-by-step explanation:
To multiply 4×5⅜, the mixed number can be broken down into a whole number and a fraction. In this case, that whole number would be 5 and the fraction would be three-eighths. Each of these parts are then multiplied by 4 and the products are added together.
4×5⅜ = 4×(5+⅜)
= 4×5 + 4×⅜
= 20 + 3/2
= 20 + 1½
= 21½
