Step-by-step explanation:
the answer is 13 when we evaluate it
Answer:
x = 9
Perimeter = 74
Area = 342
Step-by-step explanation:
First, find x. to do so, set your formula up as
18 = 8x - 54
18 + 54 = 8x
72 = 8x
72/8 = x
9 = x
Now that you have x, find your missing side
2x + 1 = y, x
2 * 9 + = y
19 = y
Your perimeter is P = 2(l+W)
P = 2(18 * 19)
P = 74
Your area is A = wl
A = 19 * 18
A = 342
10^7 is the correct answer
You can use sin 40°.
Set up the equation: sin 40° = 16/x
Isolate x: 16/sin 40° = x
Simplify: x = 24.88
So, the answer is F. 24.88
