From question, 
(140-x)/7+70=120
Or, (140-x)/7=120-70
Or,140-x=50X7
Or, -x=350-140
Or, -x=210
 :• x = -210 answers

Answer:
It's choice 2.  c = 3 sin 45 / sin 40.
Step by-step explanation:
m< A = 180 - 45-95
= 180 - 140
= 40 degrees.
So by the Sine Rule:
 c / sin 45 = 3 / sin A
Cross multiply:
c sin A = 3 sin 45
c =  3 sin 45 / sin 40.
