Question

Hello! I'm afraid I don't know which equation to use to solve this problem.

I am familiar with solving for x and other stuff, but I have a problem with finding and using the right formula. I was wondering if anyone could help me out with that? :D (Will mark brainliest too!)

Find the value of x. Show all your work for full credit.

Answer 1

Yo sup??

This question can be solved by applying the properties of similar triangles

the triangle with sides 5x and 20 is similar to the triangle with sides 45 and 35

The similarity property used here is called AAA ie angle angle angle property as all the three angles of the 2 triangles are equal.

therefore we can say

5x/45=20/36

x=5 units

Hope this helps
