Question

What is the value of ø for the acute angle in a right triangle?

sim (ø)= cos (48 degrees)

Ø=??????

Answer 1

Sin and cos are related by the following identity:

sin (90 - θ) = cos(θ)

The value of θ in the given case is 48, so the equation becomes:

sin(90 - 48) = cos(48)

sin (42) = cos(48)

Thus, in the given question value of ø will be 42 degrees.
