Question

ABCD is a trapezium with AD//BC angle A = 3x+1 and angle b = 2x+4
Find x
​

Answer 1

Answer:

35°

Step-by-step explanation:

∠A+∠B=180°.................co-interior angles of a parallel sides

∠A = 3x+1

∠B = 2x+4

∠A + ∠B = 3x+1 + 2x+4 = 180°

= 5x+5 = 180°

= 5x = 175°

therefore, x = 175/5 = 35°
