At work, Brett must check and record the internal temperature of the freezer on an hourly basis. When working properly, the
temperature should remain constant over time. What word describes the slope of a line showing the temperature of the
freezer as a function of time in hours when the freezer is working properly?
positive
zero
negative
undefined

the answer will be the last one

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
