Question

If sin x = 3/4 then the value of cos x is ​

Answer 1

Answer:

square root of 7/4

Step-by-step explanation:

because sin =perpendicular ÷hypotenous

and cos =base ÷hypotenous

and from given value of sin we know that perpendicular on nominator is 3 and hypotenous on denomiator is 4

by pathgorous theorm

hypotenous ^2 = base ^2 +perpendicular ^2

puttimg values

4 ^2 = base ^2 + 3^2

16 = base ^2 + 9

base ^2 = 16-9

base ^2 = 7

base becomes square root of 7 by taking square on both sides and cancelling square from base

so answer is

cos = base ÷hypotenus

cos = square root of 7 divided by 4
