Solution by Steps
step 1
To convert radians to degrees, multiply by 180π\frac{180^\circ}{\pi}
step 2
Multiply 133π72\frac{133\pi}{72} by 180π\frac{180^\circ}{\pi} to convert to degrees
step 3
Simplify the expression: 133π72×180π=133×18072\frac{133\pi}{72} \times \frac{180^\circ}{\pi} = \frac{133 \times 180^\circ}{72}
step 4
Cancel the π\pi in the numerator and denominator and simplify the fraction: 133×18072=133×52=332.5\frac{133 \times 180^\circ}{72} = \frac{133 \times 5^\circ}{2} = 332.5^\circ
step 5
Express the decimal in degrees and minutes: 332.5=332+0.5×60=33230332.5^\circ = 332^\circ + 0.5 \times 60' = 332^\circ 30'
[1] Answer
33230332^\circ 30'
Key Concept
Conversion from radians to degrees
Explanation
To convert an angle from radians to degrees, multiply the radian measure by 180π\frac{180^\circ}{\pi}. After multiplying, simplify the expression to get the degree measure, and if needed, convert the decimal part to minutes.
