I'll help with the question at the bottom of the page. The rest are unfortunately too blurry.

The x is the adjacent side to the reference angle. The 7 is the hypotenuse. The hypotenuse is always opposite the 90 degree angle.

Let's use the trig ratio cosine.

cos(angle) = adjacent/hypotenuse

cos(39) = x/7

7*cos(39) = x

x = 7*cos(39)

x = 5.44002 which is approximate

x = 5.4

Make sure your calculator is in degree mode.
