Answer:

5) x = 5

6) x ≈ 51.47

Explanation:

It looks like you're being asked to solve for x the equations ...

  • sin(30°) = x/10
  • cos(39°) = 40/x

Solution

These are solved in the way any such equation is solved, though you need a calculator to find the values of the trig functions.

5) sin

Multiply by the denominator:

x = 10·sin(30°) = 5

6) cos

Multiply by x, then divide by cos(39°):

x = 40/cos(39°) ≈ 51.47
