Answer:
pqr²+pr-rp²+rq²
Step-by-step explanation:
pq(r²+1)-r(p²+q²)
pqr²+pr-rp²+rq²
Remark
You must use the sin law to find this.

Multiply through by 12
12 *
*12

0.5269 = sin(x)
Now you have to use the inverse of the sine function.
Use your calculator for that
2nd F
sin-1
(0.5269)
= 31.79 degrees. <<<<<< Answer.
There sometimes is a second answer. I don't think there is in this case.
The trapezoid has two parallel sides
Answer:
B 6 centimeters
Step-by-step explanation:
y = x + 2
2x + 3y = 36
substitute y = x+2 into the second equation
2x + 3 (x+2) = 36
distribute
2x + 3x+ 3*2 = 36
combine like terms
5x+6 = 36
subtract 6 from each side
5x +6-6 = 36 -6
5x = 30
divide by 5
5x/5 = 30/5
x = 6
the short side is x =6
the longer side is
y= x+2
y = 6+2
y =8
