The dimensions of triangle b are three times the dimensions of triangle a. the area of triangle b is 364.5 cm2.

what is the area of triangle a?

Area of triangle A/Area of triangle B = (1/3)^2
Area of triangle A/364.5 cm^2 = 1/9
Area of triangle A = 1/9×364.5cm^2
=40.5cm^2

We know on the regular cosine graph, it decreases from 0 to pi. so, we need to set 0 as y.0 = 4 cos(2x-pi)0 = cos(2x-pi)2x-pi = pix = piwe already know the answer, but do pi on your own!

Infinity is the farthest from 2 on the number line
