The grade that a student scores on her math test is inversely proportional to the number of hours a week that she plays video games. she scores a 73.6 on a test when she plays 10 hours of video games per week. if this relationship continues at the same rate, what score can she expect on her math test if she plays video games for only 8 hours a week?

step-by-step explanation:

ever thing time 1 is a multiply by 1 it get  

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°.
