Answer:

75°

Step-by-step explanation:

Since the 2 angles are supplementary and TC is a perpendicular bisector, we know that m∠ATC is 90°

All we need to do is simply subtract 15° from 90° to find m∠ATB:

90 - 15 = 75°

Answer:

75°

Solution,

Let m<ATB be X

[tex]x + 15 + 90 = 180[/tex]

(sum of angle in straight line)

[tex]x + 105 = 180[/tex]

subtract 105 on both sides

[tex]x + 105 - 105 = 180 - 105 \\ x = 180 - 105 \\ x = 75[/tex]

Hope this helps ...

Good luck on your assignment..
