Answer:
Step-by-step explanation:
Use the half angle formulas
sin(θ/2) = ±√((1 - cosθ)/2)
sin(θ/2) = ±√((1 - (3/5))/2)
sin(θ/2) = ±√((2/5)/2)
sin(θ/2) = ±√(1/5)
knowing θ is in the 4th quadrant, θ/2 will be in the second quadrant where sines are positive.
sin(θ/2) = +√(1/5) = √0.2

Step-by-step explanation:
Jenny planned to solve 2/3 of homework
On Saturday she solved 28 problems, which is 7/8 of the planned number
<u>Planned number is:</u>
- 28 : 7/8 = 28 * 8/7 = 32 problems
<u>Jenny's homework was:</u>
- 32 : 2/3 = 32 * 3/2 = 48 problems
Answer:
8.5 hours
