Answer:
m ABC = 270°
Step-by-step explanation:
Note that the measure of the circle = 360°
m CA = 90°, thus
m ABC = 360° - m CA = 360° - 90° = 270°
Answer:
Let O be the center of the circle.
<COA = 90*
<FOE = <AOB = 146*
Considering that a circle is 360* we have <BOC = 124*
The Arc ABC is <AOB + <BOC = 124 + 90 =214*.
