Answer:
C) 125°
Step-by-step explanation:
Supplementary angles add to 180 degrees. Complementary angles add to 90
An angle's complement is 35°.
35+x =90
Subtract 35 from each side
35 -35+x = 90-35
x = 55
We want to find the supplement of this angle
55+y = 180
Subtract 55 from each side
55-55+y = 180-55
y= 125
The angle is 55 so its supplement is 125
7/8 can be converted to .875 because 1/8 is .125 and .125*7=.875. Add -12 to it so the answer is -12.875
1:100 because 20 divide by 20=1 and 2000 divide by 20 =100
39=3m-15
39+15=3m
54=3m
54/3=3m/3
m=18
