Question

I need help solving this pls

Answer 1

x = 44.5

Explanation:

2x + x + (x+2) = 180

4x + 2 = 180

4x = 178

x = 44.5

Just saw your last comment :)

Let me know if you have any questions!

Answer 2

x = 44.5 due to the Triangle Angle Sum Theorem

Explanation:

This is the Triangular Angle Sum Theorem.

This rule states that every angle inside the triangle has to equal 180.

This is a solve for x situation

2x + x + x + 2 = 180

Add all the x's first

3x + x + 2 = 180

4x + 2 = 180

Now subtract 2 both sides

4x = 180 -2

4x = 178

Divide 178 by 4

x = 44.5

You could verify by plugging 44.5 into the x's

2(44.5) + 44.5 + 44.5 + 2 = 180

89 + 44.5 + 46.5 = 180
