Question

If two adjacent angles of a parallelogram are 2x-22° and 3x-23°, find the value of x

Answer 1

Answer:

2x-22+3x-23=180(cointerior angles

supplimentary in Parallel lines)

3x-45 = 180

3x = 135

x=45 degree. Ans:

Answer 2

Answer:

x=45degree

Step-by-step explanation:

To find value of x

Given: two adjacent angles of parallelogram = 2x-22degree and 3x-23degree

Now, sum of two adjacent angles=180degree

equation becomes :

2x-22+3x-23 = 180

2x+3x(-22-23)=180

2x+3x-45=180

5x-45=180

5x=180+45

5x=225

x=225÷5

x=45
