Hello there! So, this is a quadrilateral and quadrilaterals equal 360 degrees. Let’s combine like terms to start off. 39x + 9 = 360. First, let’s subtract 9 from both sides to get 39x = 351. Next, divide each side y 39 to isolate the “x”. When you do that, x = 9. Now, let’s plug in the values for each, when you do, here are the final answers.
x = 9
E = 75 degrees
F = 91 degrees
G = 89 degrees
H = 105 degrees
Those are all of the angle measurements, but it wants the measurement of angle H. Therefore, that angle measurement is 105 degrees.
