Answer 1

Answer: 121

First you need to find the angle of the third unknown space within the triangle. To do this, add 57 and 64. The answer to this is 121. Then, subtract 121 from 180. The answer to this is 59. Now that you know the unknown angle within the triangle, subtract 59 from 180 to find the measure of angle 1.

Answer 2

59°

Explanation:

The total of all the angles in a triangle should amount to 180°. So:

64° + 57° = 121°

180° - 121° = 59°
