Answer:
Assuming that it's a rectangular track and the units are 15x25 yards, the perimeter is 80 yards.
Explanation:
Remember to find the perimeter of a non-circular shape you just add up all of the side lengths together. In this case, I believe it's a 15x25 yard rectangle, so you ad 15 + 15 + 25 + 25 to get a total of 80 yards.
Look at the picture.
Corresponding angles:
∠1 and ∠5
∠2 and ∠6
∠3 and ∠7
∠4 and ∠8
<h3>Therefore your answer is ∠1 and ∠5</h3>
Di you leave out some parenthesis? This looks like 3x+17x+53, which is the same as 20x+53? That is not enough information to solve. however, if you meant one angle was 3x+17 and the other was x+53, just set the two equal to each other to solve for x, then plug that into one of the equations to find the measurement of the angle.
