Question

Solve for x please help me

Answer 1

x = 30

Explanation:

One side is 90 so the other two sides have to add up to 90 too because a triangles' angles have to add up to 180.

So, we can write that 2x + x = 90

Then we can solve for x:

2x + x = 90

3x = 90

x = 30

Answer 2

30

Explanation:

all angles add up to 180*, 180-90=90, 90=3x, 30=x
