Answer:
1.31 meters
Step-by-step explanation:
Using trigonometric identities, it is found that the sine and the tangent of the angle are given as follows:
.
<h3>How do we find the sine of an angle given the cosine?</h3>
We use the following identity:
In this problem, the cosine is:
Hence the sine is found as follows:
Second quadrant, so the sine is positive, hence:
<h3>What is the tangent of an angle?</h3>
The tangent is given by the <u>sine divided by the cosine</u>, hence:
Hence:

Answer:
the length is 8ft
the width is 3ft
Step-by-step explanation:
Step one:
given
perimter= 22ft
let the length be x
width = x-5
Step two
the expression for the perimeter of a rectangle is
P=2L+2W
substituting our data
22= 2(x)+2(x-5)
open brackets
22=2x+2x-10
collect terms and solve for x
22+10=4x
32=4x
divide both sides by 4
x= 32/4
x= 8ft
the length is 8ft
the width = x-5= 8-5= 3ft
The expression: 4x² + 38x + 70 ; is a polynomial expression.
