Answer:

a. 0.5 is the answer thanks pa brainliest hahandjw

Using the trigonometry rule for the cosine, we will see that:

cos(60°) = 1/2

Remember that in a right triangle, we have that:

cos(θ) = (adjacent cathetus)/(hypotenuse)

Here we have:

•θ = 60°

•adjacent cathetus = 1

•hypotenuse = 2

Replacing all that in the equation we get:

cos(60°) = 1/2
