sin x + csc x = 2
sin x + 1/sin x = 2
(sin2 x + 1)/sin x = 2/1 (cross multiply)
sin2 x + 1 = 2sin x (subtract 2sin x to both sides)
sin2 x - 2sinx + 1 = 0
(sin x - 1)2 = 0 (take the square root of both sides)
sin x - 1 = 0 (add 1 to both sides)
sin x = 1
x = sin-1 1 = 90⁰
40x = 40(90⁰) = 3,600⁰
sin 40x = sin (3,600⁰ ) = 0
50x = 50(90⁰) = 4500⁰
sin 50x = sin (4,500⁰) = 0, so that csc 50x is undefined, we cannot divide by 0.
Then, sin40x + csc50x is undefined.
The area is 99.0 square units.
assuming that this means log5125=x, x=3.
3cos(y) = 3/(sqrt(1+x^2)
3cot(A) = 4 so cot(A) = 4/3 then tan(A) = 1/(4/3) = 3/4 and so 1 - tan(A) = 1-3/4 = 1/4
By the sine rule, sin(C)/c = sin(B)/b so sin(C) = 25/15*sin(32d15m) = 0.8894 so C = 62.8 deg or 117.2 deg. Therefore, A = 180 - (B+C) = 85.0 deg or 30.5 deg and then, using the sine rule again, a/sin(A) = b/sin(B) so a = sin(A)*b/sin(B) = 28 or a = 14.3
