Two people stand on opposite sides of a river. Person 1 stands 20 yards away from a nearby tree and person 2 views the tree at an angle of 60 degrees. To the nearest whole yard how far is it from one side of the river to the other side

*see diagram in the attachement

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)

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the 14th row will have 100 seats

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
