In the diagram, `bar(ac)` is a diameter of the circle with center o. if m`/_acb` = 50°, what is m`/_bac`? answers are  1.502.403.804.100

Answer

2. 40

Explanation

The angle subtended by the diameter to the circumference is equal to 90°.

∴ angle ABC = 90°

  Angles in a triangle = 180°

  50 + 90 + x = 180

90 + x = 180

x = 180 - 90

 = 90°

2.  

Step-by-step explanation:

Given : In the diagram, is a diameter of the circle with center O.

We know that the angle subtended by the diameter to the circumference is equal to

Using angle sum property of triangles in  , we get

Hence,

351.23
