Answer 1

A) 45

Explanation:

The shape is like a rectangle, in which all angles together would equal 360 (one angle is about 90 degrees, 90x4=360). If you add all the angles together, you recieve 315. 360-315=45.

Answer 2

a=45°

Explanation:

It should equal to 360° so if u add 115+110+90, you get 315 and you subtract that from 360. 360-315= 45
