The lower left-hand corner angle of the triangle is 85^o because it is vertical to an 85^o angle.

Since the lines are parallel, the angle supplementary to the lower right-hand corner angle of the

triangle is 98^o.

This makes the lower right-hand corner angle of the triangle 180^o - 98^o = 82^o.

Now, we know two of the three angles of the triangle; all we need to do is find the size of the

third angle. 180^o - 85^o - 82^o = .......
