Question

Which equation can be used to find the measure of angle ljk

Answer 1

If we are given a triangle JKL and we assume that this is a right triangle, we can find the measure of the angle LJK by using formulas derived from the Pythagorean Theorem.If opposite side = 10    hypotenuse = 15then, we can use: cos (x) = opposite / hypotenusesin (x) = 10 / 15
