Isabelle takes the bus to work. the bus ride to work costs her $2.50 each time. she could buy a bus pass for a one-time fee of $15.00 and would then only pay $1.00 each time to ride the bus. how many times would she have to take the bus in order for the cost to be the same?

10 times

Step-by-step explanation:

2.50 x 10 = 25

15 + (1 x 10) = 25

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°.
