Step-by-step explanation:
looking at the diagram, AC is the hypotenuse, AD is the adjacent and CD is the opposite (based on the position of the angle).
Since you are looking for CD, you would use Sine (SOHCAHTOA). Sine would be opposite over hypotenuse and following the same procedure, you will the cross multiply to get your answer
Answer:
15
Step-by-step explanation:
To get the next number you have to subtract by 9, 51-9=42, 42-9=33, 33-9=24, and so 24-9=15. The pattern is n-9 (n=previous number) and the answer is 15
