Answer:

A: 108°

Step-by-step explanation:

The trapezoid is a quadrilateral, so the sum of the total angles should be 360°.

3x + 4x + x + 2x = 360

10x = 360

x = 36

m∠A = 3 ( 36 )

m∠A = 108°

Answer:

measure if angle a is 108°

Step-by-step explanation:

measure of interior angles of quadrilateral is 360°.

therefore, 2x + 4x + 3x + X = 360°

or 10x = 360°

or X = 360/10 = 36

measure of angle A = 3x = 3 × 36 = 108°
