Answer 1

the answer is 45 how i know is i just do

Answer 2

45

Explanation:

We know that B is 90 because its a right angle, and in that triangle it has to add up to 180

So 180 - 90 = 90

90 ÷ 2 = 45

And thats a right angled triangle so it has a right angle and two equal angles.

Hope it helps :))
