Digital PSAT Math Practice Question 222: Answer and Explanation
Question: 222
In the isosceles trapezoid above, what is the measure of the smallest interior angle?
Correct Answer: 75
Explanation:
75 Isosceles trapezoids have two sets of congruent angles, and their interior angles add up to 360°. Therefore, you know that
360 = 105 + 105 + x + x. Combine like terms:
360 = 210 + 2x. Subtract 210 from both sides:
150 = 2x. Dividing by 2 tells you that x = 75. Therefore, the smallest interior angle is 75°.
