Question 1190365
the angles are supplementary.
this means their sum is 180 degrees.
you get:
2x - 20 + 3x - 25 = 180
combine like terms to ge:
5x - 45 = 180.
add 45 to both sides of the equation to get:
5x = 225.
divide both sides of the equation by 5 to get:
x = 45 degrees.
2x - 20 = 70 degrees.
3x - 25 = 110 degrees.
70 + 110 = 180
solution is x = 45 degrees.
