Answer:60°
Step-by-step explanation: First, think about the rule of the degrees for all triangles. Angles must equal 180°.
Second, because all angles must equal 180°, see that the triangle given has equal sides (assuming this, because no other measurements are given).
Equilateral triangles have equal angles, meaning 60° for each angle.
Leroi’s account
$100
After first deposit = $100+$10=$110
After second deposit= $110 + $10 = $120
Sylvia’s account
$100
10% of $100 is $10
After first deposit = $100+ $10 = $110
10% of $110 = $11
After second deposit = $110 + $11 = $121
Therefore after their first deposit, both will have the same value in their accounts.
But after the second deposit, Sylvia will have 1$ more in her account than Leroi.
The two ends of the track are semi circles, so we need to calculate the circumference:
Circumference = PI x 56 = 175.84
The two straight parts are 130 m each:
Total perimeter = 175.84 + 130 + 130 = 435.84 m
The answer is D.
