Answer 1

Answer:

hi..hope it helps you...

Step-by-step explanation:

Let angle A be 60 Degrees, let angle B be 90 Degrees, so naturally angle C is 30 Degrees. ... In a Right Angled Triangle, Cos of certain angle is defined as Adjacent Side divided by Hypotenuse. Therefore Cos(60) would be AB/AC, which is x/2x, which is 1/2. Thus it is proved that Cos(60) is 1/2.
