Given the following information, find the length of the missing side. Leave your answer as a simplified radical. Answer options:

2

2√3

4√3

8√3

2√3

Step-by-step explanation:

Our focus is going to be on Triangle CDB,

BC = 4

∠DBC = 60°

Using SOH CAH TOA, we have;

Sine  60° = opposite / Hypotenus

√3/2 = CD / 4

4 *  √3/2  = CD

CD = 2 * √3

CD = 2√3

f

step-by-step explanation:

f

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
