Answer:
b. 44/117
Step-by-step explanation:
Calculate tan(x) and tan(y) - can use calculator, or use Pythagoras' Theorem to calculate the length of the 3rd side of the right triangle (as you already have the side opposite to the angle and the hypontenuse, since sin(x) = O/A) and then determine tan(x) using tan(x) = O/A
Then use these values in the tan sum angle trig identity formula.

Answer:
30 ounces
Step-by-step explanation:
You first have to write out the two equations:
5+0.25x=y
2+0.35x=y
Then simply equal the equations to each other:
5+0.25x=2+0.35x
Subtract the 2 from both sides:
3+0.25x=0.35x
Subtract the 0.25x from both sides:
3=0.10x
Divide the 0.10 on both sides:
30=x
So, 30 ounces is your answer!
You can check by plugging 30 back into the equations to make sure that they are equal to each other.
5+0.25(30)=12.5
2+0.35(30)=12.5
The operation of this problem is B multiplication
