Answer:
sin B = 15/17
Cos B = 8/17
Tan B = 15/8
Step-by-step explanation:
This is how you work it out:
u + xy
Plug in your numbers that you know:
20 + 9 * 8
20 + 72
92
A^2+B^2=C^2
18^2+80^2=C^2
324+6400=C^2
6724=C^2
*Squareroot*
82=C
Firstly we are looking for two variables x,y so that we need two formulas .
the second formula is missing
