Question

Given the diagram below which of the following ordered pairs

Answer 1

D. (b cosC, b sinC)

Step-by-step explanation

The vertex A is a point and the coordinate of a point are given by (x, y).

cos = adjacent/hypotenuse

cosC = x/b

b cosC = x

x = b cos C

sin = opposite/hypotenuse

sinC = y/b

b sinC = y

y = b sinC
