Show that the points a(2, 2), b(5,7). c(-5, 13), and d(-8, 8) are the vertices of a rectangle.
a ab = cd = 8 bc = da = 4
b. ab = cd = 34 bc = da = 136
ac = bd = 170
ab = cd = 134 bc = da = v136 ac = bd = v170

12 yards
Step-by-step explanation:
Reference angle = 60°
Opposite side length = 20 yards
Adjacent side length = d
Applying the trigonometric function, TOA, we have:
Tan 60 = opp/adj
Tan 60 = 20/d
d × Tan 60 = 20
d = 20/Tan 60
d ≈ 12 yards (nearest whole yard)
