hello :<span>
<span>an equation of the circle Center at the
A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a = -2 and b = 1 (Center at the A(-2,1))
r = AP......P( -4 , 1)
r² = (AP)²
r² = (4+2)² +(1-1)² = 36
an equation of the circle that satisfies the stated conditions.
Center at </span></span> A(-2,1), passing through P(-4, 1) is : (x+2)² +(y-1)² = 36
The measurement of angle b is equal to 100
Answer:
b= 55 degrees
c= 125 degrees
Step-by-step explanation:
So angle B and 55 degree angle are vertical angles to they are congruent and opposite
Angle C and angle b =180 so subtract 55 from 180 to get missing angle C as 125 degrees
