Answer 1

30). D 8/17

31). A a/✓a^2+b^2

Step-by-step explanation:

30) tan ø= perpendicular/base

*tanø=15/8

So, Perpendicular is 15 and base is 8 so hypotenuse using Pythagoras theorem will be 17.

Then cos ø=Base/Hypotenuse=8/17

31) tan ø= a/b

So, Perpendicular will be a and Base will be b so hypotenuse will be ✓a^2+b^2

So, Sin ø= perpendicular/Hypotenuse= a/✓a^2+b^2.
