Answer:

41

Step-by-step explanation:

Supplementary angles sum to 180°

Sum the 2 given angles and equate to 180

3x + 2x - 25 = 180

5x - 25 = 180 ( add 25 to both sides )

5x = 205 ( divide both sides by 5 )

x = 41

Answer:

x = 41

Step-by-step explanation:

<m1 + <m2 = 180             Show the angles are supplementary

3x + 2x - 25 = 180           Substitute

5x - 25 = 180                   Combine like terms on the left

5x - 25 + 25 = 180 + 25   Add 25 to both sides    

5x = 205                           Divide by b

5x/5 = 205/5                    Do the division

x = 41
