Please take a moment to read the complete forum guidelines. (There's also a summary here.)

In short, please show what you've tried (even if you think it's wrong). It really helps the volunteer tutors, if you also explain why you're stuck or say which parts are confusing or unfamiliar.

For example, on exercise #8, we see a triangle divided into two right triangles. Do you know the meaning of those tick marks, on the base of each right triangle? If you do, what would that tell us about the two triangles, knowing that they share the same height?

8. What sort of triangle must be formed by the two smaller triangles? What does this tell you about the lengths of the two indicated sides?

9. The picture here is too small for me to read clearly. Are the angle indicators at the top left and bottom right of the square-ish figure indicators that the angles are right?

10. For the top two smaller triangles, it appears that you have SAS. What then can be said about these two triangles? What then can be said about the lengths of the two indicated sides?
