Answer:
1 and 2, 3 and 4, 5 and 6, 7 and 8
Step-by-step explanation:
Supplementary angles are angles that add up to 180°. Since 180° would basically be a straight line, those angles are supplementary
ANSWER

EXPLANATION
The area of the given triangle can be calculated using the formula,

Where b=54yd , c=54yd,and A=27° is the included angle.
We plug in these values to get;


The correct answer is D.
=3y+18y-12=2y-2-7
=21y-12=2y-9
=21y-2y=-9+12
=19y=3
Y=0,16
Answer:
c=pi x d
3.14x12.5
d is the answer
