Step-by-step explanation:
Answer:
Let the two supplementary angles be
we know sum of two supplementary angles is 180
2x + 3x = 180
5x = 180
x = 180/5
x = 36
2*36 = 72
3*36 = 108
Therefore the two supplementary angles are 72 and 108
Say base1 = 26 and base2 = 12 then your height is 18.
1/2 (18) times ( 26+12)
So that's 9 times 38=342
342 squared is your answer
Answer:
$819
Step-by-step explanation:
First we find the area of the wall so we multiply 13ft x 9ft.
13ft x 9ft = 117ft
We know each square foot is equal to $7. So now we multiply 117 x 7 to get the total cost.
117 x 7 = $819
