4/31. There's no more simplified version than that.
Answer:
A. 24
Step-by-step explanation:
Angles in a triangle add up to equal 180
Thus, 66 + 90 + x = 180
66 + 90 = 156
156 + x = 180
180 - 156 = 24
Hence, x = 24
Note: There is a right angle indicated by the square inside of the triangle. A right angle has a measure of 90 degrees. So Just in case you were wondering that's where the 90 cam from
Applying the equation for the area of the trapezoid, it is found that the height is of 10 cm.
The <em>area of a trapezoid</em> is <u>half the multiplication of the sum of the bases and the height</u>, that is:

For this problem, we have that:
, hence:





The height is of 10 cm.
