Answer:
The answer is 9.
Step-by-step explanation:
I had the question on one of my quizzes.
7/10 because you add seven and three which equals ten, and seven of them are dimes.
7^2+18^2=49+324
49+324=373
19.31^2 would be your answer
M∠B = x
m∠A = 4x
x + 4x = 180
5x = 180
x = 180/5
x = 36
m∠B = x = 36°
m∠A = 4x = 4 * 36 = 144°
Answer is <span>b. 144, 36</span>
