To make the conversion, we have to remember that 180° is equal to π radians, then:


(\pi)/(180)

We have to multiply the given degrees times the conversion:

• 45°


45*(\pi)/(180)=(\pi)/(4)\approx0.79

• 240°


240*(\pi)/(180)=(4)/(3)\pi\approx4.19

• 260°


260*(\pi)/(180)=(13)/(9)\pi=4.54

Answer:


45=(\pi)/(4)rad
240=(4\pi)/(3)rad
260=(13\pi)/(9)\text{rad}
