Question

Help me please :) thank you

Answer 1

a=90°

c=45°

b=45°

Explanation:

this triangle is a right triangle. (shown by the box in angle a) this means a must equal 90°

and by extension means the other two angles have to equal 45° each because right angles always have two angles of the same degree and the angles of a triangle always Equal 180°

Answer 2
