Question

A fashion designer made plans for solid gold earrings in the given shape. If gold costs $o.74 per mm then what will it cost to make one of the earrings

Answer 1

The question has two similar triangles. The triangles are isosceles.

In order for us to get the length of the sides of the other triangle, we can use ratio and property

Explanation:

Triangle 1

side lengths = 24 mm

base length = 16 mm

Triangle 2

side lengths = ?

base length = 11 mm

24 : 16 = X : 11

24 / 16 = X / 11

16X = 264

X = 16.5 mm
