Question

Two adjacent angles of parallelogram are 2 x + 30 and 3 x + 30 find the value of x

Answer 1

2 x + 30 +  3 x + 30 = 180° (Adjacent angles are supplementary)

5x + 60 = 180°

5x = 180° - 60°

x = 120/5°

x= 24°     :)

Answer 2

Answer:

Let 2x + 30 be equation (1)

And 3x + 30 be equation (2)

According to the condition given

Equation (1) + Equation (2) = 180....sum of sides of adjacent angles

2x + 30 + 3x + 30= 180. ... Given values

5x + 60 = 180

5x =180 -60

5x = 120

x = 120÷5

x =24

Hence value of x is 24
