Answer:
this one is supplementary and x equals 31
Step-by-step explanation:
Remember, complementary angles add up to equal 90 degrees whereas supplementary angles add up to equal 180 degrees.
In this case, since your angles together form a straight line, they're supplementary angles. Now, to solve for x:
(3x + 25) + 2x = 180 (step 1: set the equation equal to 180)
5x + 25 = 180 (step 2: combine like terms)
-25 -25 (step 3: subtrace 25, BS)
5x = 155
5x / 5 = 155 / 5 (step 4: divide by 5, BS to get x by itself)
x = 31
