Answer: (B) - 43°
Explanation: Using the sine rule, we can say that sinA/BC = sinC/AB
sin(61)/45 = sin(C)/35
sin(C) = 35sin(61)/45
sin(C) ≈ 0.680259772....
C = arcsin(0.680259772...)
C = 42.8639459...
C ≈ 43°
Move the constant to the right
5k=7-6
calculate
5k=1
solution: k=1/5 or k=0.2
Your total expense would be 35$ because 25+10=35 and then since you are talking about money you add the money sign. Your answer would be 35$
