Question

What is the value of cos(A) in the diagram? a.60/61 b.61/11 c.11/61 d.61/60

Answer 1

Answer:

A

Step-by-step explanation:

cosA = $\frac{adjacent}{hypotenuse}$ = $\frac{AC}{AB}$ = $\frac{60}{61}$ → A

Answer 2

Answer:

a. 60/61

Step-by-step explanation:

With reference angle A

base(b) = 60

hypotenuse (h) = 61

Now

Cos(A) = b / h

= 60/ 61
