Question

Can you help me please ?

Answer 1

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.
