Question

Triangle ABC is similar to triangle WYZ.

Select all angles whose cosine equals 3/5

Angle Y



Angle A



Angle B



Angle C



Angle W



Angle Z

Answer 1

∠B

∠Y

Explanation:

we know that

In the right triangle ABC

----> opposite side to angle B divided by the adjacent side to angle B

substitute the values

Remember that

If two triangles are similar, then the corresponding sides are proportional and the corresponding angles are congruent

so

∠A=∠W

∠B=∠Y

∠C=∠Z
