Answer:
108
Step-by-step explanation:
Remark
You need to define Remote Interior Angle in order to solve this. The definition has two parts.
Interior: means means inside something. In this case it means inside the triangle.
Remote: (In this case) not connected to.
Givens
- Exterior Angle: 2a
- Remote interior angles: a + 10 and 44
Equation
2a = a + 10 + 44 Combine the right side
Solution
2a = a + 54 Subtract a from both sides
2a - a = a - a + 54 Do the subtraction
a = 54
Answer
a = 54
2a = 2*54
2a = 108
