Angle DAC = 180-25 = 155 degrees
Angle ABC = 180 - 146 = 34 degrees
Angle ADC = 180 - 149 = 31 degrees
ABCD is a quadrilateral and angles in quadrilateral add up to 360 degrees
Angle BCD = 360 - (155 + 34 + 31)
= 360 - 220
= 140 degrees

The measure in radians for the central angle of the circle is; 0.9 radians.
<h3>What is the angle measure in radians of the central angle?</h3>
Since, the length of the arc is given as 7.2cm and it's radius is 8cm.
It follows that the angle measure of the central angle can be evaluated as follows;
7.2 = (A/6.28) × 2× 3.14 × 8
7.2 = 8A
A = 7.2/8
A = 0.9 radians.
