Given GH is tangent to ⊙T at N. If m∠ANG = 54°, what is mAB ? A circle with centre T is given. GH is tangent to the circle which touches the circumference of the circle at point N. From N, a diameter NTB is drawn. A chord AN is also given, this chord forms an acute angle with tangent. mAB = 72 °

mAB=72°

Step-by-step explanation:

Theorem:The angle between a Tangent and a Radius is 90 degrees.

Applying the above theorem therefore:

∠ANG+∠ANB=90°

54°+∠ANB=90°

∠ANB=90°-54°

∠ANB=36°

Now, Inscribed Angle= of the measure of the arc

Therefore:

36°= mAB

mAB=36*2=72°

answer: 12
