Question

Use abc to find the trigonometric ratios. Enter your answer as fractions

Answer 1

Tan <A = 4/3

Cos <A = 3/5

Sin <A = 4/5

Explanation:

From the diagram given

Hypotenuse AB = 10

Adjacent = 6

Opposite = 8 (side facingc<A)

According to SOH CAH TOA

Tan <A = Opposite/adjacent

Tan <A = BC/AC

Tan <A = 8/6

Tan <A = 4/3

For Cos <A;

Cos <A = adj/hyp

Cos <A = 6/10

Cos <A = 3/5

For sin<A:

Sin <A = opp/hyp

Sin <A = 8/10

Sin <A = 4/5
