Answer:

68°

Explanation:

Equations:

To solve for y we have to use the sine rule which is defined as:


(sinA)/(a) =(sinB)/(b) =(sinC)/(c)

Side a is opposite from angle A, side b is opposite from side B, etc.

Solving for y:

Let's say angle A was the angle we are trying to find. Then we can re-write the sine rule as:


(sin(y))/(250) =(sin(48))/(200)

Let's re-arrange this for the angle y:


sin(y)=250 * (sin(48))/(200) \\y=sin^-1(250 * (sin48)/(200) )

Typing this into a calculator gives the answer:
y = 68.26... which is 68 degrees rounded to the nearest whole degree.
