Kevin was asked to determine the length of side XZ. His
work is shown
Which error did Kevin make?
He has the side lengths in the wrong place in the
cosine ratio
18
He multiplied both sides by the length of XZ instead
of dividing by XZ
He should have used the sine ratio.
He should have used the tangent ratio
1 cos(34°): 1
2 (XZ)cos(349) = 18
