Answer 2

The correct answer is B. 144°

Explanation:

Let's recall that in a trapezium the bases are parallel and one of its properties is that the two angles on the same side are supplementary, that is the sum of the angles of two adjacent sides is equal to 180°.

Upon saying that, we can find out the value of a and b, this way:

∠a = 180 - 36

∠a = 144

∠b = 180 - 113

∠b = 67

But the question is regarding ∠a. Then the correct answer is B. 144°
