Answer 8

For the first one, use the fact that the sum of all the angles in a triangle equal 180.

Number 2, you just need to solve for the supplementary angle and do the same as the first one

On the third, the angles bdc and bda are 90 degrees, so you can solve for the remaining angles in the 2 triangles inside the bigger one (bdc and bda)

And i cant really help you on proofs, so the last one is on your own.
