A horse is tied with a rope in the center of grassland to graze. The length of the rope is 5m. The diameter of the circular gard
marin [14]
The length of the rope with which the horse is tied becomes the radius of the circular area.
Length of rope = 5 m
Area within which the horse can graze
= pi * r^2 = 3.14 * 5 = 15.7 m^2
Area of the grassland at the Centre of which the horse is tied = 3.14 * 25
= 78.5 m^2
Area in which the horse cannot graze
= Area of grassland - Area in which the horse can graze
= 78.5 - 15.7
= 61.8 m^2

Cos(−θ)=−√2/5 , sinθ>0 What is the value of sinθ ?
mel-nik [20]

Answer:

sin theta = +(√23)/5

Step-by-step explanation:

Did you know that the cosine is an even function, so that cos (-theta) = cos (+theta)?

Thus we have:

cos(θ)= −√2/5 , sinθ>0

If the cosine of theta is negative, that means that the terminal side of theta is in either Quadrant II or III.  Since the sine of theta is positive, we can deduce that theta is in Quadrant II.

Given cos(θ)= −√2/5, we square both sides, obtaining (cos theta)^2 = 2/25.  Using the formula (sin theta)^2 + (cos theta)^2 = 1, we arrive at:

(sin theta)^2 = 1 - 2/25, or 23/25.

Then sin theta = +(√23)/5.
