Question

If cos ⍬ = 1 2 , sin ϕ = 1 2 , find ⍬ + ϕ

Answer 1

Answer:

90

Step-by-step explanation:

hello mate

it could be 1/ 2 in both cases as values of sin and cos lies between -1 and 1.

cos (theta) = 1/2 is given the value of cos is 1/2 when the angle is 60 so theta will be 60

given sin (phi) = 1/2

value of sin is 1/2 when angle is 30 since sin 30 = 1/2

so phi is 30

so totally he has asked to find theta + phi

which is equal to 60 + 30

that is 90

hope it helps you
