Question

two measures of two adjacent angel on a straight line are x° and ( 2x - 27 )° find each angel ​

Answer 1

we know that the sum of two adjacent angles on a straight line in 180° .

here the angles are x and 2x -27

therefore

x +2x - 27 =180

3x = 180 +27

3x = 207

x = 207/3

x = 69°

2x-27=138−27=111  degrees
