Answer:
Option C. ![\frac{9}{6}=\frac{15}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B6%7D%3D%5Cfrac%7B15%7D%7Bx%7D)
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent
In this problem
![\frac{AB}{DE}=\frac{BC}{CD}](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7BDE%7D%3D%5Cfrac%7BBC%7D%7BCD%7D)
substitute the values
Answer:
measure of exterior angle at C = 160°
Step-by-step explanation:
An exterior angle of a triangle equals the sum of the two remote interior angles
A and B are the remote interior angles. So,
m∠A + m∠B = measure of exterior angle at C
5x - 10 + 12x = 16x
17x - 10 = 16x
x = 10
measure of exterior angle at C = 16x = 16(10) = 160°
You have to muliply it all togeather to get the exact answer. 4 times 10 equals 40 40 times 3 equals 120 then 120 times 6 equals 720 and thats the right answer
