How to find y in angle sum theorem
Svetach [21]

Answer:

y = 90°

Step-by-step explanation:

  • 110° is the measure of exterior angle of bigger triangle.

  • -> (x + x) + 70° = 110° (By exterior angle theorem)

  • -> 2x = 110° - 70°

  • -> 2x = 40°

  • -> x = 40°/2

  • -> x = 20°

  • y is the measure of exterior angle of smaller triangle.

  • -> y = x + 70° (By exterior angle theorem)

  • -> y = 20° + 70°

  • -> y = 90°

Paladinen [302]

Answer:

i think the answer is 125.66 (or 125.6 if you use 3.14 as pi)

Step-by-step explanation:

First find the area of the blue circle by multiplying pi times the radius squared to get 380.13 (or 379.94 if multiplied 3.14)

Then find the area of the orange circle by doing the same thing to get 254.47

(or 254.34 if multiplied by 3.14)

finally subtract 380.13-254.47 to get 125.66.

(or 125.6)
