Question

Can I please get some help with this problem?

Answer 1

a = 55

Explanation:

By exterior angle theorem:

a+10 + 44 = 2a

a= 55

Here's the proof:

Consider the same figure shown

say a+10 = x and 44 = y

Thus the remainng angle is 180 - x-y

and the exterior angle is 180- ( 180 - x- y) = x+y

Thus proved
