Question

the opposite angles of parallelogram are 3 x minus 2 degree and 50 minus x degree find the measures of each angles
​

Answer 1

Given two opposite angles of a parallelogram are (3x − 2)º and (50 − x)º Recall that opposite angles of a parallelogram are equal. Hence (3x − 2) = (50 − x) ⇒ 3x + x = 50 + 2 ⇒ 4x = 52 ∴ x = 13 (3x − 2)º = [3(13) − 2]º = [39 − 2]º = 37º Sum of adjacent angles is 180º Hence other two equal opposite angles = 180º − 37º = 143°

Answer 2

Measures of opposite angles of a parallelogram are 3x 2 and 50 x

Two opposite angles of a parallelogram are( 3x-2)º and (50-x)º two opposite angles of a parallelogram are( 3x-2)º and (50-x)º.find the measure of each angle of the parallelogram. Recall that opposite angles of a parallelogram are equal.
