Answer:
Step-by-step explanation:
You know that ...
- cos(θ)² = 1 - sin(θ)²
- tan(θ) = sin(θ)/cos(θ)
- cosine is negative in the third quadrant (where π < θ < 3π/2)
Using what you know about the relationships of these trig functions, you can find ...
cos(θ)² = 1 - ((-√3)/2)² = 1 - 3/4 = 1/4
cos(θ) = -1/2 . . . . . negative square root of 1/4
__
tan(θ) = sin(θ)/cos(θ) = ((-√3)/2)/(-1/2)
tan(θ) = √3
<span>So we want to know how can we use numbers 2, 3, 5, 8 to get 104. There are two ways to do it. First way: (2*5-3)*8=(15-3)8=13*8=104 and the second way is pretty similar to the first way (2*5+3)8=(10+3)8=13*8=104. So those are the two ways to get 104 using those 4 numbers.</span>
The value of the number can be equal to or less than -3

Answer:
49 seconds
Step-by-step explanation:
The time perry used is 7/8 of a minute
a minute equals to 60 seconds
so the time perry used is 7/8 x 60 = 52.5 seconds
The winner used 14/15 of 52.5 seconds (perrys time)
so 14/15 x 52.5 = 49 seconds
