Question

What is the value of cos x
Answer fastttttt

Answer 1

cos x = 30/34 or 15/17

Explanation:

SOH CAH TOA

side a is 30 (adjacent)

side h is 34 (hypotenuse)

cos= a/h

Answer 2

The value of cos X is 15/17. Option C

To determine the value of the identity, we need to know that the different trigonometric identities are listed as;

• sine
• cosine
• tangent
• cotangent
• secant
• cosecant

Now, the ratio for the cosine identity is expressed as;

cos X = adjacent/hypotenuse

From the diagram, we have that;

Adjacent = 30

Hypotenuse = 34

Substitute the values

cos X = 30/34

cos X = 15/17
