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

A

Explanation:

cosA =
`(adjacent)/(hypotenuse)` =
`(AC)/(AB)` =
`(60)/(61)` → A

Answer 2

a. 60/61

Explanation:

With reference angle A

base(b) = 60

hypotenuse (h) = 61

Now

Cos(A) = b / h

= 60/ 61
