So I am taking this Trig class and it is kicking my little bunns. I need help with my homework and I managed to get a little help earlier today but I'm still lost. Can anyone help me please? Thank you to anyone who helps me with this.

1. Find the length of the arc (to the nearest tenth of a unit) intercepted by each angle with r = 9cm: 240 degrees

a. ≈37.7 cm

b. ≈21.60 cm

c. ≈12.36 cm

d. ≈515.66 cm

2. For questions 2-5 Use the given sides and or measures of angles of a right triangle to find the requested side and/or angle. In each case y=90 degrees. alpha = 23.4 degrees: find B.

a. 156.6 degrees

b. 66.6 degrees

c. 6.6 degrees

d. 180 degrees

3. If a = 6.3 and b = 47 degrees: find b

a. ≈ 4.61

b. ≈ 4.30

c. ≈ 6.76

d. 5.59

4. a = 5.31 and c = 7.27: find alpha

a. ≈ 0.73 degrees

b. ≈ 0.01 degrees

c. ≈ 46.92 degress

d. ≈ 43.08 degrees

5. a = 6.2 and b = 9.3: find c

a. ≈ 7.55

b. ≈ 56.93

c. ≈ 3.24

d. ≈ 2.75

e. ≈ 3.29

6. Solve for the triangle alpha using law of cosines with 3 sides given as a = 3.4, b = 2.7 and c = 1.3

a. ≈ 111.6 degrees

b. ≈ 68.4 degrees

c. ≈ 47.6 degrees

d. ≈ 20.8 degrees

7. Solve for the triangle beta using law of cosines with the 3 sides given as a = 3.4, b = 2.7 and c = 1.3

a. ≈ 111.6 degrees

b. ≈ 68.4 degrees

c. ≈ 47.6 degrees

d. ≈ 20.8 degrees
