In circle a, tangent fh and chord eg intersect to form angle heg. find the measure of angle heg. a. 36 degreesb. 72 degreesc. 144 degreesd. 216 degrees

Option B is correct, i.e. 72 degrees.

Step-by-step explanation:

Given is a diagram of circle in which tangent-chord angle is formed i.e. angle ∠HEG.

We can find the angle ∠HEG using the Tangent-Chord Angle formula as follows:-

Tangent-chord angle = Half of intercepted arc.

angle ∠HEG = 1/2 arcEG.

(3x + 18) = 1/2 * (9x - 18)

6x + 36 = 9x - 18

9x - 6x = 36 + 18

3x = 54

x = 18.

angle ∠HEG = 3x+18 = 3*18 + 18 = 72 degrees.

Hence, option B is correct, i.e. 72 degrees.

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

the correct is answer is a 9-sided polygon!
