Answer :
(A) The distance from point A to point B to the nearest tenth of a foot will be 3.4 ft.
(B) The value of 0 to the nearest tenth of a degree will be 54.8°
SOH, CAH, and TOA are the trigonometry ratios that need to be solved in order to find necessary measures or angles in a right triangle.
A) Reference angle = 28 degrees
Distance A-B = ?
Adjacent = 3 ft
We will calculate the distance between A-B by using the trigonometry function, CAH, that is:
Cos ∅ = adj ÷ hyp
Cos 28° = 3 ÷ A-B
A-B = 3 ÷ Cos 28°
A-B = 3.4 ft
B) Reference angle = ?
Distance A-B = 5.2 ft
Adjacent = 3 ft
We will calculate the distance between A-B by using the trigonometry function, CAH, that is:
Cos ∅ = adj ÷ hyp
Put the values
Cos ∅ = 3 ÷ 5.2
∅ = Cos⁻¹ (3 ÷ 5.2)
∅ = 54.8°
