ANSWER

( {x - 11)}^{2}  + ( {y - 5)}^{2}  = 16

EXPLANATION

The given circle has center:

(11,5)

and

radius: 4

The equation of a circle with center (h,k) and radius , r is given in standard form as;

( {x - h)}^{2}  + ( {y - k)}^{2}  =  {r}^{2}

We substitute the values into the formula to obtain,

( {x - 11)}^{2}  + ( {y - 5)}^{2}  =  {4}^{2}

( {x - 11)}^{2}  + ( {y - 5)}^{2}  = 16

Flauer [41]
A) Measure of Angle L is 67.5. Angle F & Angle L are alternate interior angles.

b) Measure of Angle E is 112.5, because we know that F and H are vertical angles, so therefore they’re congruent. We also know H and E are adjacent, so H + E = 180.

c) Angles E and K are alternate exterior angles. Measure of Angle K is 112.5.

d) Measure of Angle H is 67.5, because we know that Angle F, which is vertical to Angle H, is 67.5. Vertical angles are congruent.

e) Measure of Angle I is 112.5, because Angle I and Angle K are vertical angles.

f) They’re corresponding angles.
