Question

If cos x = 4/5, Find the value of Sin x?

Answer 1

Answer:

GIVEN,

cos x = 4/5

FIND,

Sin x

Step-by-step explanation:

SOLUTION

So,

Using Trigonometric identities: Sin2x = 1- Cos2x

Sin2x = 1 – (4/5)2

▶ 1 – 16/25

▶ (25 – 16) / 25

▶ 9/25

▶ Sin x = √9/25

▶ 3/5

Hence,

the value of sin x is 3/5

Answer 2

the value of sin x is 3/5

it is your answer
