Answer:
c = 127°
Step-by-step explanation:
∡c and ∡a are supplementary angles.
Supplementary angles sum 180°
∡a = 53°
Then:
53° + c = 180°
c = 180° - 53°
c = 127°
For #2, ∠3 and ∠1 are supplementary. You know that the measure of ∠1 is 162°, so what is ∠3? 180-162=18.
m∠3=18° if ∠1=162°.
Hope this helped!
42 because it is all of the sides have to be added up for the perimeter so the formula would be 14+14+7+7.
Answer:
2-2 goes with 1 - 1
10 - 7 goes with 8 - 5
4 - 3 goes with 7 - 6
8 - 2 goes with 9 - 3
9 - 5 goes with 5 - 1
Have a nice day.
