Answer:

Step-by-step explanation:

ΔAOC is an isosceles triangle as OC = OA ----> RADIUS

42 + 42 + ∠AOC = 180   {Angle sum property}

       84 + ∠AOC = 180

              ∠AOC = 180 - 84

∠AOC = 96°

y = 96/2    {Central angle theorem}

y = 48° ------------(I)

∠B + ∠D = 180    {sum of opposite angles of Cyclic  Quadrilateral}

x + y = 180

x + 48 =  180        {from (I) }

x = 180 - 48

x =  132°

If you travel 4 miles around a circle with a radius of 1 mile, what is the central angle (q)?
mixer [17]

Answer:

229.18 degrees

Step-by-step explanation:

The circumference of a circle with radius r is 2×pi×r.

So if it has a radius of 1 mile, then the circumference is 2×pi×1=2pi miles.

So if we travel 4 miles, then the percentage of this circle we traveled is 4/(2pi)=63.66% approximately.

There are 360 degrees in a circle and we want to how much of that rotation belongs to traveling 4 miles of the circumference of a circle that measures 2pi miles. So 63.66%×360 degrees =229.18 degrees.

Identify the perimeter show work
Helen [10]

Answer:

60

Step-by-step explanation:

The perimeter is the measurement around an object.

So first you multiply the 20 and the 10 by 2.

20 * 2 = 40

10 * 2 = 20

Then, add then up!

40 + 20 = 60
