60 = (10 + 20 + 30 + 40 + x)/5
300 = 100 + x
x = 200
Answer: 200
The answer is 44. ! Your welcome
You need the Law of Sines for this. In our case we have the measure of angle B and side b, we have the measure of angle A and are looking for side a, or x. Setting up the Law using our info, we have

. We will solve for x by multiplying both sides by sin(42):

, first choice above.
Answer:
Express s in terms of v and t
s= v/t, multiplying both sides of the equation by t
Express t in terms of v and s
t= s/v ( from s=vt)
Step-by-step explanation:
The answer for this problem would be : true
