I need help with my math.the problem is in the picture below.

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,
[tex]\begin{gathered} m\angle C=m\angle Y=35 \\ m\angle D=m\angle W=55 \\ m\angle E=m\angle X=90 \end{gathered}[/tex]
