117 degrees
The angles in a trapezoid add up to 360 degrees. 63 x 2 = 126
360 - 126 = 234
234/2 = 117
Answer:
see below
Step-by-step explanation:
Vertical angles are formed by two lines and are opposite each other
Vertical angles are equal
3.4x3=10.2...
hope this helps!!
The answer would depend on where the numbers you gave us are on the pyramid. but here is the formula to find the surface area of a prism;
surface area= base x height + 2 x length x side + length x base
i will do the equation for you if you specify which numbers are the base, length, side, and height. or if you attach a photo.
