Answer 1

Let the altitude be AF , SO, FC = √(20²-12²) = 16

Now siny = AF/AC = 3/5 and coty = 4/3 .

Also AB =√{12²+5²} = 13.

Sinx = 5/13 now the value of expression is 10/sinx +6/siny -6coty = 10*13/5 +6*5/3 -6*4/3 = 26+10-8 = 28.

Answer 2

Answer:

the evolut evaluate 10 6 siny= 6 coty is (B) 21
