Question

5. sin 30°= 1/2 and cos 30° = √3/2
A.True
B. False

6. Check all that apply. If sinθ = 15/17 , then:
A. tanθ = 15/8
B. cscθ = 17/15
C. secθ = 17/8
D. cosθ = 17/8

7. Check all that apply. If secθ = 13/12 , then:
A. cosθ = 12/13
B. cscθ = 12/13
C. sinθ = 12/13
D. tanθ = 5/12

Answer 1

5 is true

Answer 2

now lets try n#6

Answer 3
