<h3>Answer</h3>
a = 36
b = √3/5
════════════════════
<h3>Known </h3>
Adjuscent = 12√3
════════════════════
<h3>Question</h3>
Opposite = ?
Hypotenuse = ?
════════════════════
<h3>Way to do</h3>
• finding a - opposite
#use tan formula
tan(∅) = opposite / adjuscent
tan(60) = opposite / 12√3
opposite = tan(60) × 12√3
opposite = 36
•finding b - hypotenuse
#use cos formula
cos(∅) = adjuscent / hypotenuse
cos(60) = 12√3 / hypotenuse
hypotenuse = 12√3 : cos(60)
hypotenuse = √3/5

8/5 = 1 3/5
(5 x 1 = 5 + 3 = 8, to get 8/5)
13/12 = 1 1/12 (12 x 1 = 12 + 1 = 13, to get 13/12)
Hope this helped! :D
slope intercept form
y=mx+b
x-y =2
we need to subtract x from each side
x-y-x = -x +2
-y = -x+2
multiply each side by -1
-1*-y = -1(-x+2)
y = x -2
the slope intercept form is
y = x-2

Answer:
97.42 square units
Step-by-step explanation:
The area of a sector is given by ...
A = (1/2)r²θ
where r is the radius (12.2) and θ is the central angle in radians. Here, you're given the central angle as 75°, so you need to convert that to radians.
75° = (75°)×(π/180°) radians = (5/12)π radians
Then the area is ...
A = (1/2)(12.2²)(5π/12) = 744.2π/24 ≈ 97.42 . . . square units
__
Equivalently, you can find the area of the circle in the usual way:
A = πr² = π(12.2²) ≈ 467.59465
Then, multiply by the fraction of the circle that is shaded (75°/360°)
sector area = (467.59465)(75/360) = 94.42 . . . square units
Answer:
third one
Step-by-step explanation:
area = pi * R^2 = pi * 1^2 = pi ft^2
