Answer:

a = 54

Step-by-step explanation:

In geometry, the angles in a triangle add up to 180.

The unmarked angle at the top of the triangle = 180 - (a+10+44)

Or you could say that same angle = 180 - 2a because it is supplementary to the exterior angle... so

2a = a + 10 + 44

2a-a = 54

a = 54
