Quadrilatorals

MCQ - 108-11960

Question:

The angles of a quadrilateral measure x°, x°, (x + 45)°, (x + 65)°. Evaluate x.

x=65
x=70
x=67.5
x=70

Correct Answer: D

Explanation:

The sum of the degree measures of the angles of a quadrilateral is 360, so we can set up and solve for x in the equation:

x + x + (x + 45) + (x + 65) = 360

4x + 110 = 360

4x + 110 − 110 = 360 − 110

4x = 250

4x ÷ 4 = 250 ÷ 4

x = 62.5
