Answer 1

Draw a line through the middle of the top corner down to the base that divides the triangle in two pieces. Then you have a 90° angle with the base.

You know that u = 180° - 106° = 74°

Then you have the top corner of the left triangle to figure out, you do the following;
Since all triangles add up to 180°, you can do 180°-90°-74° = 16°

This is half the corner of the big triangle. Simply multiply 16° by 2 and get 32°.
