An exterior angle of a triangle is an angle formed by one side of the triangle and the extension of an adjacent side of the triangle. FACTS: ... The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.
C.21 ft x 48 ft
because you multiply 7 by 3 and 12 by 3 and that is what it is
The answer is 106 degrees. This is because 22 degrees + 52 degrees + 106 degrees = 180 degrees, completing the angles.
Hope this helps!
