Answer:
α ≈ 76°
Step-by-step explanation:
The vertices of a rectangle are right , that is 90°
Using the tangent ratio in right triangle ABC
tanα =
=
=
= 4, then
α =
(4) ≈ 76° ( to the nearest degree )
Answer:
x = 8
Step-by-step explanation:
In order for the triangles to be similar, corresponding side must be in proportion.
So, FE/ZY = FD/ZX
6/12 = (2x - 5)/22
6(22) = 12(2x - 5)
132 = 24x - 60
24x = 192
x = 8
