Given two similar triangles
So, the corresponding angles are congruent, and the corresponding sides are proportional
As shown:
m∠ Y = 35, m∠ X = 90
So, m∠ W = 90 - 35 = 55
And the triangle XYW is similar to the triangle ECD
So,

Answer:
4/3
Step-by-step explanation:
You add the top numbers and not the bottom then simplify.
Answer:
= 18
Step-by-step explanation:
= 
Cross multiply
5 * c = 30 * 3
5c = 90
Divide both sides by 5
c = 90/5
c = 18
