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.
49. Straight lines always equally 180 degrees. And the angle directly below P is equivalent to the 131 angle so 180-131=49 (hope that was somewhat explained well enough because angles are hard to explain without directly showing on paper)
Answer:
base of the triangle = 12 m
Explanation:
Area of the triangle = 1/2 * base * height
We are given that:
area = 54 m^2
height = 9 m
Substitute in the equation to get the base as follows:
Area of the triangle = 1/2 * base * height
54 = 1/2 * base * 9
108 = 9*base
base = 12 m
Hope this helps :)
