Question 7
a. In the given figure, if LATO = 40°, find LAOB

​

Answer 1

Answer:

Angle AOB=140°

Step-by-step explanation:

In the quatdrilateral TAOB, TAO and Angle TBO are both equal to 90° for being tangent to the circle from the external point T.

Since, the sum of all the internal angles of quadrilateral is 360°, then leaving the two right angles, the remaining angle should sum up to 180°

So,

Angle ATO + Angle AOB = 180°

40°+ Angle AOB = 180°

Angle AOB = 180°- 40°

Angle AOB = 140°
