In the triangle below, what is the length of the side opposite the 60° angle?
A. 3 sq root of 3
B. 3
C. Square root of 3
D. 6

B

Step-by-step explanation:

(opp/hyp)=sin60

opp=2sqr(3)x(sqr(3)/2)

opp=3

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
