You decide to go shopping online. You purchase a pair of shoes that cost
$50 and 4 identical t-shirts. Your total comes to $220. What is the price of
each shirt?

42.5

Step-by-step explanation:

You substract the cost of the shoes from the total which is $220-$50=170 and then you divide it by the amount of t-shirts

170/4= 42.5

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°.
