Solution by Steps
step 2
Next, we convert this fraction to an angle in degrees. Since a full circle is 360360^\circ, we multiply the fraction by 360360^\circ: 100180×360\frac{100}{180} \times 360^\circ
step 3
Simplifying the multiplication: 100180×360=100×360180=36000180=200\frac{100}{180} \times 360^\circ = \frac{100 \times 360}{180} = \frac{36000}{180} = 200^\circ
Key Concept
Fraction to Angle Conversion
