Answer:
<P = 56 degrees
Step-by-step explanation:
Given the following
m<R = 90 degrees
QR = 61feet = Adjacent
RP = 90 feet= Opposite
Required
tan<P = opp/adj
Tan<P = 90/61
<P = arc tan (90/61)
<P = arctan 1.4754
<P = 55.9
<P = 56 degrees to the nearest degree
Answer:
1/2
Step-by-step explanation:
The "Pythagorean relation" between trig functions can be used to find the sine.
<h3>Pythagorean relation</h3>
The relation between sine and cosine is the identity ...
sin(x)² +cos(x)² = 1
This can be solved for sin(x) in terms of cos(x):
sin(x) = √(1 -cos(x)²)
<h3>Application</h3>
For the present case, using the given cosine value, we find ...
sin(x) = √(1 -(√3/2)²) = √(1 -3/4) = √(1/4)
sin(x) = 1/2
__
<em>Additional comment</em>
The sine and cosine of an angle are the y and x coordinates (respectively) of the corresponding point on the unit circle. The right triangle with these legs will satisfy the Pythagorean theorem with ...
sin(x)² + cos(x)² = 1 . . . . . . where 1 is the hypotenuse (radius of unit circle)
A calculator can always be used to verify the result.

Answer:
The area of the rectangle is 4 sq yards.
Step-by-step explanation:
Given that,
The length of the rectangle, ![L=\dfrac{2}{13}\ yards](https://tex.z-dn.net/?f=L%3D%5Cdfrac%7B2%7D%7B13%7D%5C%20yards)
The breadth of the rectangle, B = 26 yards
We need to find the area of the rectangle. The formula for the area of a rectangle is given by :
A = LB
Put all the values,
![A=\dfrac{2}{13}\times 26\\\\A=2\times 2\\\\A=4\ yd^2](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B2%7D%7B13%7D%5Ctimes%2026%5C%5C%5C%5CA%3D2%5Ctimes%202%5C%5C%5C%5CA%3D4%5C%20yd%5E2)
So, the area of the rectangle is 4 sq yards.
