Answer:
∠ 1 = 102°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 1 is an exterior angle of the triangle , then
∠ 1 = 33° + 69° = 102°
102
exterior angle rule:
an exterior angle of a triangle is equal to the two opposite interior angles
so m1= sum of opposite interior angles (69 and 33)
69+33=102
so m1 = 102
I would assume you're supposed to solve for x and multiply that by 8 for the perimeter. Like I said in the comment, I'm not a math major.
