An angle measures 158° more than the measure of its supplementary angle. What is the measure of each angle?

11

Step-by-step explanation:

x+x+158=180

2x=180-158

2x=22

x=11

Smaller angle is 11 degrees

Larger angle is 169 degrees.

Step-by-step explanation:

Supplementary angle makes up a total of 180 degrees.

x = smaller angle

x + x + 158 = 180

  2x + 158 =180

            2x = 22

               x = 11

Larger angle is x + 158 or 169.

12*c

step-by-step explanation:

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to
