Answer:
a. Find the measure of each central angle.
The central angle of a circle = 360 °
Now Pie is cut into 10 equal sectors
Angle of each sector is given by
Angle of sector = Total central angle/number of sectors


Hence , the central angle of one slice of pie is 36°
b. If the diameter is 50 in., find the length of an arc of one of the sectors.
length of an arc of one of the sectors =



$ 3042
Explanation
we need to use the formula:

Step 1
a)let

b) now, replace

therefore, the answer is
$ 3042
Answers:
x = 7
The measure of angle D is 14 degrees
-----------------------------------------------
-----------------------------------------------
Angle C and angle D are complementary, which means they add to 90 degrees.
(angle C) + (angle D) = 90
(12x-8) + (3x-7) = 90
12x-8 + 3x-7 = 90
(12x+3x) + (-8-7) = 90
15x-15 = 90
15x-15+15 = 90+15
15x = 105
15x/15 = 105/15
x = 7
So you have the correct x value. Nice work.
Now use this x value to find the measure of angle D
angle D = 3*x - 7
angle D = 3*7 - 7
angle D = 21 - 7
angle D = 14 degrees
Answer:
214
Step-by-step explanation:
set bc = to cd and solve for x
then substitute x into one of the equations and solve --> you should get 73
multiply 73 by 2 and then subtract that from 360
you should get 214
