It is given that two lines are parallel, and hence the corresponding angles are congruent, by corresponding angles postulate. It is also given that the triangles in the photo share an angle, by the reflexive property, the shared angle is congruent. Hence one can use angle-angle to determine that the two triangles in the picture are similar.
Using this, one can set up a proportion with the sides. The ratios of any two corresponding sides are the same as any other two corresponding sides in the triangle, respectively, this is due to the corresponding parts of similar triangles theorem.

A set of biology exam scores are normally distributed with a mean of 70 points and a standard deviation of six points X equal the score on a randomly selected exam from the set find P(X< 73)
Answers
Answer: .69
Step-by-step explanation:
Answer on khan
We can write the value in the range P(64 < {x} < 76) as 0.68.
What is standard deviation?In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values.
Given is that a set of biology exam scores are normally distributed with a mean of 70 points and a standard deviation of six points X equal the score on a randomly selected exam from the set.
It is given that -
μ = 70
σ = 6
For the range of {x}, we can write -
(μ - σ) < {x} < (μ + σ)
64 < {x} < 76
We can write the range of {z} value as -
(64 - 70)/6 < {z} < (64 + 70)/6
- 1 < {z} < + 1
Now -
P(64 < {x} < 76) = P(x < 76) - P(x < 64) = 0.84 - 0.15 = 0.68
Therefore, we can write the value in the range P(64 < {x} < 76) as 0.68.

using compound interest, how long does it take to double a 1000 dollar investment that pays 6.5% annual interest, compounded monthly?
Answers
Answer:
11 years approx
Step-by-step explanation:
Given data
P=$1000
A=2000
R=6.5%
T= ?
Calculate time, solve for t
t = ln(A/P) / r
substitute
t=ln(2000/1000)/0.065
t=ln(2)/0.065
t=0.693/0.065
t=10.66
Hence the time is 11 years approx

Consider the sequence of steps to solve the equation: 2(x – 4) + 6x = 9x – 10
Given = 2(x - 4) + 6x = 9x - 10
Step 1 = 2x - 8 + 6x = 9x - 10
Step 2 = 2x + 6x - 8 = 9x - 10
Step 3 = 8x - 8 = 9x - 10
Step 4 = 8x – 8x - 8 = 9x - 8x - 10
Step 5 = 0 - 8 = x - 10
Step 6 = -8 = x - 10
Step 7 = -8 + 10 = x - 10 + 10

Question Help
Think About the Process A jar contains only pennies, nickels, dimes, and quarters. There are 29
pennies, 16 dimes, and 17 quarters. The rest of the coins are nickels. There are 74 coins in all. How
many of the coins are not nickels? If n represents the number of nickels in the jar, what equation could
you use to find n?
Answers
Answer:
62 coins are not nickels. you could just add the pennies, dimes, & quarters. those totals are given. So
29+16+17= 62
or if you want to impress then start with the total and subtract each given coin count
74-29-16-17=12
74-12=62
∠A and \angle B∠B are complementary angles. If m\angle A=(2x-10)^{\circ}∠A=(2x−10) ∘ and m\angle B=(x-2)^{\circ}∠B=(x−2) ∘ , then find the measure of \angle A∠A.
Answers
Answer:
118°
Step-by-step explanation:
Two angles are called complementary when their measures add to 90 degrees.
From the question,
Angle A=(2x-10)°
Angle B=(x-2)°
Both Angles are complementary.
Therefore
Step 1
(2x - 10)° + (x - 2)° = 180°
2x + x - 10 - 2 = 180°
3x - 12 = 180°
3x = 180° + 12
3x = 192°
x = 192/3
x = 64°
Step 2
We are to solve for Angle A
(2x-10)°
Angle A = 2(64 ) - 10
Angle A = 128 - 10
Angle A = 118°
The measure of Angle A = 118°
