A+B+C = Pi
B + C = Pi - A
cos(B +C)= cos (Pi -A)
cos (B+C) = -(cos A)
-(cos A) = cos(-A)
so that,
cos(B +C) = cos(-A)
now we cut cos
B+C = -A//
(3/5)y =57
3y =5 * 57
y =(5* 57) /3
y = 19 * 5
y = 95//
that is a good answer frnd.
6/8
6 number / 2 and 8 number/2
3/4
that is the answer......
(2x - 3) ^ 2
4x^2 -12x +9
3 + 5 ^0
3 + 0

3 - 4x > -6
-4x > -6 -3
-4x > -9
x < -9/-4
x < 9/4
