Here are 2 right triangles. Part A: Explain how you know the right triangles are similar

Part B: Write a ratio that is equivalent to z/x

Part C: Which ratios of side length are equal to tan(a)

Part D: Explain why the values of the trigonometric ratios only depend on the angle and not on the particular lengths x, y,z, q,r, s

Part E: If y/z=O.7, what is the measure of to the nearest degree?

​

Answer

Part A: The right triangles are smiliar because If the lengths of the hypotenuse and a leg of a right triangle are proportional to the corresponding parts of another right triangle, then the triangles are similar.

Part B: 2z:2x or 2z/2x. You can write z/x as z:x. Then just multiply both sides by the same number to get an equivalent ratio. Let's multiply by 2. then the answer will be: 2z:2x or 2z/2x
