I dont understand this at all, I need the right anwser and Explanation please.

a = 7; b = ⁷/2

Step-by-step explanation:

Recall the acronym, SOHCAHTOA

We would apply trigonometric ratio formula in finding a and b.

Reference angle = 60°

Opposite side to the reference angle =

Adjacent side = b

Hypotenuse = a

✔️To find a, we would apply SOH, which is:

Plug in the values

(sin 60 = √3/2)

Cross multiply

Side both sides by √3

Divide both sides by 2

a = 14/2

a = 7

✔️To find b, apply TOA, which is:

Plug in the values

(tan 60 = √3)

Cross multiply

Divide both sides by √3

Divide both sides by 2

b = 7/2

investment b is an ordinary annuity with $3,909.64 in the account after one year.
