Question

(2x+5)^0 and (3x-10)^0 are supplementary angles . Find x​

Answer 1

2x +5 + 3x -10 = 180

5x = 180 +5

x = 185/5

x = 37

please mark me as brainliest

Answer 2

Answer:

(2x+5) + (3x-10) = 180

[ sum of supplementary angles is 180° ]

=> 2x + 5 +3x - 10 = 180

=> 5x - 5 = 180

=> 5(x - 1) = 180

=> x - 1 = 180/5

=> x - 1 = 36

=> x = 37°
