Answer:
1=110 degrees given
2=70 degrees
3=80 degrees
4=100 degrees
Step-by-step explanation:
1=110
2=180-110=70
3=1/2(100+60)=80 by the angle formed by two chords theorem
4=1/2(80+120)=100 by the angle formed by two chords theorem
Answer:
I. (x - 6)² + (y + 7)² = 121
Step-by-step explanation:
Given a circle with coordinates of the center as (6, -7), and with a diameter of 22, equation of the circle is given below using the standard equation formula of a circle:
Formula => (x - a)² + (y - b)² = r²
Where,
a = 6
b = -7
r = radius of circle = ½ of diameter = ½ of 22 = 11
Thus, plug in the above values into the standard equation formula:
(x - 6)² + (y - (-7))² = 11²
(x - 6)² + (y + 7)² = 121
<em>Our answer, which is the equation of the circle is I. (x - 6)² + (y + 7)² = 121</em>

The solution is actually pretty simple. All you have to do is plug the numbers in corresponding the letters like a with a b with b and calculate
7). 6(6)+(5)^2-(3)^2=52
And you do the same thing with 8) you get 180
A -3 subtracted by 10 is -13 and it stays 2
Okay. I’m no mathematician, but I’m pretty sure it would be 995/90 = h. I used the “/” as the divide symbol. This would be the equation because you need to divide the total by the cash per hour to be able to get the number of hours the plumber worked. I really hope this helps!
