Answer:
area of circle=πr²=1.3mi²
we have
area of sector=∅/360×πr²
0.7mi²×360=∅1.3
∅=0.7×360/1.3=193.846°×π/180=387.7 radian
Answer:
x = 7/12
Step-by-step explanation:
Solve the exponential problem :
1/16=64^4x-3
1 / 4^2 = 4^3(4x - 3)
4^-2 = 4^3(4x - 3)
-2 = 3(4x - 3)
-2 = 12x - 9
-2 + 9 = 12x
7 = 12x
7/12 = 12x/12
7/12 = x
Hence, x = 7/12
The sides of a regular polygon with a known interior angles can be found as follows:
Interior Angle = (n−2) × 180° / n
<h3 /><h3 /><h3>Regular polygon</h3>
A regular polygon is a polygon that have equal sides and equal angles.
A regular polygon has the following angles:
- interior angles
- exterior angles
According to the question, the interior angles are given. To know the number of sides of polygon can be calculated as follows:
Note the interior and the exterior angles add up to 180 degrees.
Therefore,
Interior Angle = 180° − Exterior Angle
Exterior angle = 360°/n
Interior Angle = 180° − 360°/n
n = number of sides
Finally,
- Interior angle = (n−2) × 180° / n

Classic trigonometry:
theta is 60
adjacent side is 10
find opposite side
soh cah toa
sin cos tan
use tangent
tan = O/A
so tan(60) = O/10
multiply by 10 each side
10tan(60) = O
Opposite = 17.32"
