Answer:
They are complementary angles.
Step-by-step explanation:
62° + 28°
= 90°

The ball reaches its maximum height after 3.5 seconds, and the maximum height is 61.025 meters.
1, 3, 5, 7. 1 and 3 they are vertical meaning they are congruent. 3 and 5 are alternate interior angles meaning they are congruent. 7 and 5 are vertical so they are congruent.
Given cy - 7 = 5d + 3y, we solve for y as follows:
cy - 3y = 5d + 7
y(c - 3) = 5d + 7
y = (5d + 7) / (c - 3)
