A group of students are playing a game in which each player attempts to toss a beanbag through a hole cut in a piece of plywood. Players earn points for successful tosses and lose points for missed tosses. Results for two players
are shown in the table.

the answer is b.

step-by-step explanation:

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours

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°.
