Well, since it is asking for an average, we have to add
78+89+87+96=
350... then we divide by 4
which would be 87.5 which IS greater than 80 :)
and less than 90 :)
Let's say that ST is side b
<span><span>Use the Law of Sines to find side b.</span><span>
b / sin(B) = a / sin(A)</span><span>
b / sin(59°) = 7 / sin(79°)</span><span>
b = (sin(59°) x 7) / sin(79°)</span><span>
b = 6.112
That is answer B.) 6.1 yards
Hope this helps!</span></span>
