Answer:

Sin theta 3/5

Cos theta 4/5

Step-by-step explanation:

Draw the triangle and label the O as 3 and A adjacent as 4. Find H hypothenus using theorem pythagoras and you'll get 5.

Then put inside the formula of sin theta = O/H

and cos theta is A/H

Value of Sinθ and Cosθ are 3/5 and 4/5

Given that;

Tan θ = 3 / 4

Find:

Sinθ and Cosθ

Computation:

Tan θ = Perpendicular / Base = 3 / 4

So,

Perpendicular = 3 unit

Base = 4 unit

Hypotenuse = √P² + B²

Hypotenuse = √3² + 4²

Hypotenuse = √9 + 16

Hypotenuse = √25

Hypotenuse = 5 unit

Sinθ = Perpendicular / Hypotenuse

Sinθ = 3 / 5

Cosθ = Base / Hypotenuse

Cosθ = 4 / 5
