Answer one that hasn’t been answered

4x + 2x = < y

This is because the opposite sides (which is 4x and 2x) of a triangle add up to the exterior angle (<y).

We have to find X.

As you know:

because the angles of a triangle add up to 180.

When we add them:

The 9 is multiplying with the X. We want X only and not 9 with it. So, when we take 9 to the other side, it becomes divide. As a result, the answer to x is:-

Substitute value of x into 4x and 2x to find the exterior angle:-

4x:

2x:

When we add them we get the answer for angle Y:-

Therefore, we can conclude that:

so what is the question
