Q2 of 40 Page 8

Two adjacent angles of a parallelogram are (2x + 30)˚ and (3x + 30)˚. Find the value of x.

Given: adjacent angles of a parallelogram are (2x + 30)˚ and (3x + 30)˚

To Find: Value of x.


Concept Used: Adjacent angles of a parallelogram are supplementary, i.e., Sum of adjacent angles of a parallelogram = 180˚


Explanation:


(2x + 30)˚+ (3x + 30)˚ = 180˚


(5x + 60)˚ = 180˚


5x = 180˚ - 60˚


5x = 120˚


x = 24˚


Hence, the value of x is 24˚.
