8.3: Trigonometry

Notes Any right triangles with congruent angles need not necessarily have congruent side lengths…however, they will always have equivalent side length ratios. These are called trigonometric ratios. These can be recalled using the mnemonic SOHCAHTOA

What are the sine, cosine, and tangent of angle T?

What is the measure of angle x?

What is the measure of angle T?
