Answer:
13π/4 , 21π/4, -3π/4, -11π/4
Step-by-step explanation:
Coterminal Angles are angles which share the same initial side and terminal sides.
To find coterminal angles, simply add or subtract 360° or 2π to each angle, depending on whether the given angle is in degrees or radians.
5π/4 =(4π/4)+(π/4)
Our Angle 5π/4 is in the 3rd quadrant and exceeds π radians by (π/4) radians, or 45° angular measure.
The 2 positive co-terminal angles would be:
Adding 2π
5π/4 + 2π = 13π/4
Adding another 2π
5π/4 + 2π +2π = 21π/4
The two negative co-terminal angles would be:
Subtracting 2π
5π/4 - 2π = -3π/4
Subtracting another 2π
5π/4 - 2π -2π = -11π/4
The coterminal angles are:
13π/4 , 21π/4, -3π/4, -11π/4
(35 + 47 + 42 + x) / 4 = 50
(124 + x) / 4 = 50....multiply both sides by 4, cancelling the 4 on the left side.
124 + x = 50 * 4
124 + x = 200
x = 200 - 124
x = 76 <===
D. 10 inches
As the radius is half the diameter
Distance: (sqroot(x2-x1)^2 + (y2-y1)^2)
sqroot(1-3)^2 + (8-6)^2
sqroot(-2)^2 + (2)^2
sqroot(4) + 4
Square root of 8 = 2.82843
Round to nearest tenth
