A square pyramid has a base side length of 20.4 cm and a height of 18.2 cm. Which square pyramid is similar? base side length = 18.2 cm, height = 20.4 cm base side length = 22.9 cm, height = 20.7 cm base side length = 30.6 cm, height = 27.3 cm base side length = 40.8 cm, height = 45.5 cm

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
