Question

Find the value of the variable and the measure of each angle.

Answer 1

x = 37

Explanation:

So the 3 angles inside a triangle always add up to 180 degrees. With that being said, we can get the equation:

2x + 4 + 2x - 9 + x = 180

Combine the like terms:

5x - 5 = 180

5x = 185

x = 37

2(37) + 4 + 2(37) - 9 + (37) = 180
