Question

Sine, Cosine, Tangent question below

Answer 1

3 / 5

Explanation:

TOA-CAH-SOH

TOA-CAH-SOH are 3 trigonometry ratios. They are:

TOA - tan(theta) = Opposite ÷ Adjacent

CAH - cos(theta) = Adjacent ÷ Hypotenuse

SOH - sin(theta) = Opposite ÷ Hypotenuse

Solution

We are finding Cos(A)

Cos(A) = Adjacent ÷ Hypotenuse

= AB ÷ AC

=

`(30)/(50) \\ = (3)/(5)`

Therefore Cos(A) = 3 / 5.
