Tristan wants to ride his bicycle 27 miles this week. He has already ridden 9 miles. If he rides for 6 more days, which tape diagram could be used to represent the context if
X represents the average number of miles he would have to ride to meet his goal?

an altitude of 15,000 feet

step-by-step explanation:

the answer is:

mean: 6

mad: 2.14

there were a lot of them but the first one to pop up on a google search was bts

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°.
