In the diagram, AC is a diameter of the circle with center 0. If m ZACB = 50°, what is ZBAC?

Snowcat [4.5K]

Answer:

40degrees

Step-by-step explanation:

Find the diagram attached

Since the triangle ina semi circle is a right angle, hence <B = 90degrees

Also frm the diagram

<A + <B + <C = 180

<A + 90 + 50 = 180

<A + 140 = 180

<A = 180 - 140

<A = 40degrees

Hence the measure if m<BAC is 40degrees
