The answer is 67°.
Since the parallel sides of a trapezoid are called bases, the bases in our given trapezoid are AB and DC. We know that the corresponding pairs of base angles, such as ∠A and ∠D, or ∠B and ∠C, are supplementary, therefore, their angles add up to 180 degrees:
∠A + ∠D = 180°
∠B + ∠C = 180°
Given that m∠A = 113°, we can calculate for the measure of ∠D:
113° + ∠D = 180°
∠D = 180° - 113° = 67°

Answer:
Since there are two cars, each car, then, drove 104/2 = 52 miles. But one car is traveling 8 miles per hour faster.
Step-by-step explanation:
VARIABLES:
[x] Yearbook Club (expression: x)
[y] Drama Club (expression: x + 12)
EQUATIONS:
#1 x + y = 72
#2 y = x + 12
Now we shall use the method of substitution to solve.
FINDING X:
#1 x + (x + 12) = 72
#2 2x + 12 = 72
#3 2x = 60
#4 x = 30
The amount of students in the yearbook club: 30
The amount of students in the drama club: 72 - 30 = 42
