Answer:
270 in²
Step-by-step explanation:
The area of a parallelogram is given by the formula A = bh.
The base of the parallelogram is 9+9 = 18 inches.
The height of the parallelogram is 15 inches.
This makes the area 15(18) = 270 in²
Answer:
x ≈ 8.66
Step-by-step explanation:
Using the sine ratio in the right triangle
sin60° =
= 
Multiply both sides by 10
10 × sin60° = x, thus
x ≈ 8.66 ( to 2 dec. places )
Supplementary means adds to 180
A+B=180
B=73
A+73=180
minus 73 both sides
A+73-73=180-73
A+0=107
A=107
A=107 degrees
