Find the exact value. cos150°

Aloiza [94]

ANSWER

$\cos(150 \degree) = - \frac{ \sqrt{3} }{2}$

EXPLANATION

We want to find the exact value of cos(150°).

150° makes an angle of 30° with the positive direction of the x-axis and it is also in the second quadrant.

The cosine ratio is negative in the second quadrant.

Using the unit circle,

$\cos(150 \degree) = - \cos(30 \degree) = - \frac{ \sqrt{3} }{2}$

Use PEMDAS:

P Parentheses first

E Exponents (ie Powers and Square Roots, etc.)

MD Multiplication and Division (left-to-right)

AS Addition and Subtraction (left-to-right)

A. 14 + 2 × 5 = 14 + 10 = 24 ≠ 22

B. (14 + 2) × 5 = 16 × 5 = 80 ≠ 22

C. 24 - 6 ÷ 3 = 24 - 2 = 22

D. (24 - 6) ÷ 3 = 18 ÷ 3 = 6 ≠ 22
