Answer: 1 is 149 and 2 is 70
Step-by-step explanation: the hint actually provides a lot of information using the information we can use the sum of m angle 1 and m angle 2 to get the exterior angle this is known as the exterior angle theorem
By adding the 2 angles of 63 and 86 we can get 149 that is the answer for number one
2 is a bit different because we already have the exterior angle but not one of the interior angles this is a problem that can be solved by the interior angle theorem by subtracting the exterior angle by the fixed interior angle we can get 70 those are the answers
