Plzz solve it with explanation....

THIS IS FOR THOSE WHO KNOW...

IF U ANSWER EVEN THOUGH U DON’T KNOW,
THEN U R A DONKEY....

Answer 1

Answer:

sin^-1[(√7+3√8)/12]

Step-by-step explanation:

we have,

sin^-1(1/3)+sin^-1(3/4)

as we know,

sin^-1(x)+sin^-1(y) = sin^-1[x√(1-y²)+

y√(1-x²)]

so, in above question:

sin^-1[1/3√(1-9/16)+3/4√(1-1/9)]

= sin^-1[1/3×√7/4+3/4×√8/3]

= sin^-1[(√7+3√8)/12] ...ans.
