If the shapes are similar, the correspondent sides are in proportion:
Let's plug the values and solve for x:
Multiply both sides by x to get
The only feasible solution, though, is , because it wouldn't make sense to have negative lengths.
Answer:
Y ≈ 59.0°
Step-by-step explanation:
Using the Cosine rule
cosY =
with x = 22, y = 20, z = 18
cosY =
=
= , then
Y = (
) ≈ 59.0° ( to the nearest tenth )
