To find the angle measure of a circle, you first have to think about how a circle is 360 degrees around. If you're looking for the angle measure of 9 kids out of a total of 15, you'd have to divide 360 by 15 (which is 24) and then multiply that by the number of students you're counting, which is nine students. So, 9 times 24 is 216, which is your central angle
Answer:
1/3
Step-by-step explanation:
4/12 find greatest common factor with is 4
divide both by 4
4 divide by 4 equals 1
12 divided by 4 equals 3
so is 1 over 3
Answer:
Step-by-step explanation:
CA and CB are both opposite equal 90 degree angles so are equal so we can say
8x-12=4x
4x-12=0
4x=12
x=3, since CA=4x
CA=4(3)=12
The perimeter of a rectangle is given by:
P = 2W + 2L
Where,
W: width
L: long
Substituting the values we have to:
P = 2 * (33 + 2 * (3)) + 2 * (39 + 2 * (3))
P = 168 feet

joe needs to enclose the garden and path 168 feet of fencing material
Answer:
13/22
Step-by-step explanation:
There are 9 blue cards and 13 green cards for a total of 22 cards
P (green) = number of green cards/ total cards
=13/22
