Question

Measure of opposite angles of a parallelogram are (x + 20)^0 and (2x - 30)^0 .Find the value of x and measure of each angle.​

Answer 1

Step-by-step explanation:

Given : measure of opposite angles of a parallelogram are X + 20 degree and 2 x minus 30 degree.

To find: value of x and measure of each angle

Solution:

we know opposite angle of a parallelogram are equal

this means

x + 20 = 2x-30

x-2x = -30-20

x = 50

measure of angles of the parallelogram is (50+20) = 70 degree and 180-70= 110 degrees

measure of angles of the parallelogram is 70 degree, 110 degree ,70 degree and 110 degree.
