What is the value of cos30°

Eddi Din [679]

Answer:

√3/2 or 0.866

Step-by-step explanation:

Use special triangles. (See attachment)

The cosine ratio is adjacent ÷ hypotenuse.

cos30° = √3 ÷ 2 = √3/2

As a decimal, cos30° ≈ 0.866

Remember all the primary trig ratios with the acronym SohCahToa.

"o" = opposite

"a" = adjacent

"h" = hypotenuse

S, C and T are sin, cos, tan
