Question

two adjacent angles of a parallelogram are 3 x -4 and 3 X + 10 find the value of x​

Answer 1

hey mate!

3x - 4 + 3x + 10 = 180 degree ( because adjacent angles of a parallelogram are supplementary)

so, 6x + 6 = 180

6x = 180 - 6 = 174 degree

x = 174/6 = 29 degree

hope this helps you

pls mark it as brain list

thanks❤❤
