Question

Convert the degree measurement to radians. Express answer as multiple of π: 45°A. π/6B. π/4C. π/3D. π/5

Answer 1

`45º=(\pi)/(4)`

To convert degrees to radians, we use:

`\alpha=\theta\cdot(\pi)/(180)`

Where θ is the angle in degrees and α the angle in radians.

Then:

`\alpha=45º\cdot(\pi)/(180)=(\pi)/(4)`
