Question

what is the value of tanq if sinq=4/5​

Answer 1

Answer:

sinq=4/5 so cos q=√(1-sin^2q)=√(1-16/25)=3/5.

Answer 2

Answer:

tan q=3/4

Step-by-step explanation:

sin q= 4/5

sin q= opposite/hypotenuse

let,

opposite=4x

hypotenuse=5x

hence,

adjacent=3x (from pythagorean triplets 3,4 and 5)

tan q= opposite/adjacent

tan q=3x/4x

tan q=3/4
