Area of a rectangle = length * width
So in this since, the area of the shaded area (which Is the whole rectangle)
A = 200ft * 100ft
A = 20,000
.0018529956763434 is my calculated answer.<span />
cos0 = √3/2
1 - cos²0 = sin²0
= 1/4 = sin²0
sin in quadrant 4 is negative
sin0 = -1/2
Answer:
23) option c
JL ≈ 9.3
25) option c
y ≈ 9.6
Step-by-step explanation:
<h3>25)</h3>
Given in the question that,
cos(21°) = 9 / y
y = 9/cos(21°)
y = 9.64
y ≈ 9.6(nearest tenth)
<h3>23)</h3>
Given in the question that the hypotenuse of right angle triangle = 12
To find,
height of the right angle triangle
angle k = 39°
so by using trigonometry identity
cos(39) = opp/hypo
cos(39) = JL / KL
JL = cos(39)(12)
JL = 9.32
JL ≈ 9.3

Answer:
x = 5
Step-by-step explanation:
Just use the Pythagorean Triangle:
13^2 - 12^2 = x^2
x^2 = 25
x = 5
