You will need to know that the sum of "two complementary angles" is 90
therefore
Let x = one angle
then
90-x = second angle
.
Now, we construct our equation based on the sentence:
"The sum of the measures of two complementary angles exceeds the difference of their measures by 86°."
x + 90-x = x-(90-x)+86
90 = x-90+x+86
90 = 2x-90+86
90 = 2x-4
94 = 2x
47 degrees = x (first angle)
.
Second angle:
90-x = 90-47 = 43 degrees (second angle) hope it helps
Answer:
C x=40, y=30
Step-by-step explanation:
Remember the opposite side of parallelogram is the same
so angle C and angle A is the same.
3x=120
divide both sides by 3 and you get 40
All parallelogram equal to 180 degrees so to find y
180=2y+120
-2y=120-180
-2y=-60 negative divide negative is positive.
y=30
