one of the ideas that you have explored in previous courses is how to describe a set of data. one of the ways that you may
have seen before is finding an average (also called a mean). read the math notes box for this lesson to review what a
mean is and how to find it. then find the mean for each set of data below. homework
2. jane's quiz scores: 82.64.73.91.85
b. the number of cats your teammates have as pets: 0.1.3.2
c. the number of minutes pam talked on the phone: 35.40, 12, 16, 25, 10

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

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°.
