Answer:
28 degrees
Step-by-step explanation
Extend the downwards facing line upwards past to the point
it intersects the top line going to the left, after this we have a
straight line which angle adds up to 180, so 180-98=82, then
simply the opposing angles are equal to eachother so the top
side angle of the triangle is 82, then the bottom angle is again
since opposing angle its going to be 70, then simply 180- (70+82)
which is equal to 28, voila!
