 A.  Solve each right triangle. In each case, C = 90°. If angle information is given in degrees and minutes, give answers in the same way. If given in decimal degrees, do likewise. When two sides are given, give angles in degrees and minutes

1. A = 28.00°, c = 17.4 ft.                             6. A = 61.00° , b 39.2 cm

2. B = 73.00°, b = 128 in.
7. a =958 m, b = 489 m
%3D
3. a = 76.4 yd, b = 39.3 yd
8. b = 219 m, c = 647 m
%3D
4. B = 39°9', c = 0.6231 m
9. A = 13°47', c = 1285 cm
5. A = 61.00°, c = 29.7 m
10. B = 82°51', c = 4.825 cm

B. Solve the problems below.
1. The sides of a rectangle are 13.2 inches and 7.83 inches. Find the degree
measure of the angle the diagonal makes with the longer side.
2. Find the base and the altitude of an isosceles triangle if one of the equal
sides is 5.21cm and one of the base angles is 25°20'.
3. A kite is held fast by a taut line 220 ft long. If the line makes an angle of
21°40' with the horizontal, how high is the kite above the ground when its
line is fastened to a post 6 ft above the ground.
