Let sin⁻¹( $\frac{ \sqrt{3} }{2}$ ) = x
Therefore, sin(x) = $\frac{ \sqrt{3} }{2}$
x should lie in first quadrant because √3 and 2 both are positive.

Therefore, sin(x) = 60° = π/3

Ryan Katie and Mike are roommates. They need to pay an electric bill. The bill is $155.52 The billing cycle is from nov23-dec23.

rusak2 [61]

Answer: Step-by-step explanation:

if I am correct.. Katie is gonna be paying $77.76. Meanwhile, Mike and Ryan are paying $38.88

half of 155.52 = 77.76

half of 77.76 = 38.88

$77.76 + $33.88 + $38.88 = $155.52

LUCKY_DIMON [66]

So first of all we can't start by changing them both into improper fractions

So it would be:
5/2 divided by 13/8
From there you would do 5/2 * 8/13 which could convert to
5/1 * 4/13 which would be 20/13
