Answer: 9/41</h3>
==========================================================
Explanation:
We have a triangle with these three sides.
Use the pythagorean theorem to find b
a^2+b^2 = c^2
b = sqrt(c^2 - a^2)
b = sqrt(82^2 - 80^2)
b = sqrt(324)
b = 18
This is the missing vertical leg of the triangle. And this is also the side opposite angle C.
We have enough information to compute the sine of the angle.
sin(angle) = opposite/hypotenuse
sin(C) = AB/AC
sin(C) = 18/82
sin(C) = (9*2)/(41*2)
sin(C) = 9/41
QR || ST & QT=RS
That could be an isosceles trapezoid. Don't check this one.
QR=ST & QR || ST
Congruent Parallel sides. CHECK ME.
QT || RS & QR=ST.
Basically the same as the first, don't check.
QR=ST & QT=RS
Quadrilateral with equal opposite sides is a parallelogram. CHECK ME
QR=ST & ST=ST
ST=ST is not news. Congruent opposite sides. Don't check me.
