Question

question 5 of 10
what is sin 60°?
a. $sqrt{3}$
b. $\frac{1}{2}$
c. 1
d. $\frac{sqrt{3}}{2}$
e. $\frac{1}{sqrt{3}}$
f. $\frac{1}{sqrt{2}}$

Explanation:

Step1: Recall sine definition

$\sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}$

Step2: Identify sides for 60°

Opposite side: $\sqrt{3}$; Hypotenuse: 2

Step3: Calculate sin 60°

$\sin60^\circ=\frac{\sqrt{3}}{2}$

Answer:

D. $\frac{\sqrt{3}}{2}$
