blank 1:

Explanation:

Step1: Find the third - interior angle

The sum of interior angles of a triangle is 180°. Let the third interior angle be $x$. So $x = 180-(108 + 25)=180 - 133=47^{\circ}$.

Step2: Find the exterior angle

The exterior angle of a triangle is equal to the sum of the two non - adjacent interior angles. The exterior angle (the angle marked '?') is equal to the sum of the two non - adjacent interior angles of the triangle. So the exterior angle $?=108 + 25=133^{\circ}$.

Answer:

133
