Answer:
The perimeter is approximately 19.
Step-by-step explanation:
Three of the sides are roughly four segments long and two are around three and a half.
4 + 4 + 4 + 3.5 + 3.5 = 19
12a)
5x + 45 + 3x - 25 = 180
8x + 20 = 180
8x = 160
x = 20
12b)
2x - 5 = 2(20) - 5 = 40 - 5 = 35
3x - 25 = 3(20) - 25 = 60 - 25 = 35
y = 180 - (35+35)
y = 180 - 70
y = 110
Answer:
5P= 2P+21+45 ( sum of two sides is is equal to
the opposite exterior angle)
5P=2P +61
5P-2P=61
3P=61
p= 61÷3
p=2.33333
List the degrees from least to greatest ie, 11,7,7,6,4,3 then the first is ur degree. So the answer is D. 11
Answer:

Step-by-step explanation:
So, you basically want the equation of the circle.
Given:
Center(C): 

The equation of circle is:

Where,
represents the center point and
is the radius of the circle.
Plotting the values in the equation:


This is the equation of the circle of center (5, 2) and radius 3.
