Math Question

7. Here are 2 right triangles.
a. Explain how you know the right triangles are similar.
b. Write a ratio that is equivalent to \( \frac{5}{x} \).
c. Which ratios of side lengths are equal to \( \tan (a) \) ?
d. Explain why the values of the trigonometric ratios only depend on the angle \( \alpha \) and not on the particular lengths \( x, y, z, q, r, s \).
e. If \( \frac{y}{2}=0.7 \), what is the measure of \( \alpha \) to the nearest degree?
