Answer:
x = 27
Explanation:
First of all the equation written on the question is incorrect, like not the image, this is because the angle of 3x + 10 and 3x - 28 is not the same, The equation will be 3x + 10 + 3x - 28 = 180
=> 6x - 18 = 180
=> 6x = 180 - 18
=> 6x = 162
=> x = 162 / 6
=> x = 27
Hope it helps :) If I am wrong, please consider telling me......
