You ride through some wet paint on your bike, creating a red spot on the tire. Write a cosine equation to model the height of the red spot over the distance you ride . Your bike tire has a radius (r) 13 inches The period is the circumference of the tire (2pi * r) Start the cycle when the spot is at the top of the tire.

you would need to also lose 1 point for each of the other outcomes for it to be fair.

step-by-step explanation:

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°.
