of the angles below m the units a Consider the angle depicted in Figure A i What is the measure of the angle in units of 1:4 of the circumference? 83 1/4\'s of the circumference Preview n. What is the measure of the angle in units of 1/2 of the circumference? a 1/2s of the circumference Preview ii. What is the measure of the angle in units of the circumference? w of the circumference Previevw

Solution

a) The angle in figure A represents 45.

(i) 1/4 units of circumference represents 90. So, the measure of the angle in 1/4 units of circumference is 1/2

(ii) 1/2 units of circumference represents 180. So, the measure of the angle in 1/2 units of circumference is 1/4.

(iii) Units of circumference represents 360. So, the measure of the angle in units of circumference is 1/8.

b) The angle in figure B represents 45.

(i) 1/4 units of circumference represents 90. So, the measure of the angle in 1/4 units of circumference is 1/2

(ii) 1/2 units of circumference represents 180. So, the measure of the angle in 1/2 units of circumference is 1/4.

(iii) Units of circumference represents 360. So, the measure of the angle in units of circumference is 1/8.
