Solve the equation and it will add up to -6 so
3×-7=-21
-21-10=-31
-31+25=-6
Answer:
Angle A is 37 degrees, Angle B is 82 degrees, Angle C is 61 degrees
Step-by-step explanation:
Exterior angles are the supplement of interior angles, so subtract 143 from 180 to find Angle A.
180 - 143 = 37
All angles add up to 180.
37 + 61 = 98
180 - 98 = 82
Angle B is 82 degrees.
Hope this helped. :)
The answer would be B.
For these, you plug in 8 where there ia a variable. 2(8)-1=15
