Help me solve the problems that are circled. Thank you.

C Solve for x in each of the following right triangles: 45 1. 2. x+2 X 6 h 450 60 A B 3 S D y Problems 3 and 4 refer to Figure 1. (Note: s is the distance from A to D, and y is the Figure 1 distance from D to B.) 3. In order, find h, r, y, and x if s = 5V3. 4. In order, find x, h, s, and r ify = 3. D 5. Figure 2 shows two right triangles drawn at 90 to one another. Find the length of DB if DA = 6, AC = 5, and BC = 3. 6. Through how many degrees does the hour hand of a clock move in 3 hours? 7. Find the remaining sides of a 30-60-90 triangle if the longest side is 5. 8. Graph the line 2x + 3y = 6. 9. Find the distance between the points (4, - 2) and (- 1, 10). 10. Find the distance from the origin to the point (a, b). A 11. Find x so that the distance between (- 2, 3) and (x, 1) is V13. Find sin 6, cos 0, and tan 0 for each of the following values of 0: 12. 90 13. - 450 B In which quadrant will O lie if Figure 2 14, sin 0 0 15. csc 0 > 0 and cos 0
