Question

I need help simple explanation if possible

Answer 1

3.97 because if the longest side of the triangle is the square root of both of the shorter sides square root added together. since the square root of 36 is 6, find what the square root of 4.5 is. 20.25. subtract that from 36. 15.75 then find the square root of 15.75

Answer 2

x = 3

Explanation:

if the triangles are similar then the side lengths must be proportional:

8/6 = 4/x cross multiply expressions

8x = 24 divide both sides by 8

x = 3
