I need help with question C

Fist, you have to know to use the sin rule

This is because we have to find what x is equal to (which is the hypotenuse)

Then we have to realise that we also have 2m, which is the opposite side (because it's the opposite angle to the adjacent side)

Then we make an equation

sin30 degrees = 2 divided by x

Move x to the left side and move sin30 degrees to the right side

So our equation is

x= 2 divided by sin30

Which is 4.

So x is equal to four metres.

Ithink your answer is b
