The equation for the leg length, y is y = (P - 2x - 4)/2
The length of the leg "y" is 3 feet
a) Given the perimeter of the trapezoid expressed as:
P=2x + 2y + 4.
We are to make <em>y the subject of the formula </em>as shown:
P = 2(x+y) + 4
P - 2x = 2y + 4
P - 2x - 4 = 2y
Swap
2y = P - 2x - 4
y = (P - 2x - 4)/2
Hence the equation for the leg length, y is y = (P - 2x - 4)/2
b) Give that P = 26 feet and x = 8feet
y = (P - 2x - 4)/2
y = (26 - 2(8) - 4)/2
P = 26-20/2
P = 6/2
y = 3 feet
This shows that the length of the leg "y" is 3 feet

- 1 , 0 , 1
the answer is C
Answer:
See below :)
Step-by-step explanation:
If you want a missing angle or side in one pair, and you have at least one side and angle pair, use the sine rule.
If you want a remaining side, and you have the other two sides and the angle opposite the unknown side, use the cosine rule.
If you want an angle, and you have all three sides, use the cosine rule rearranged for angles.
