Question

(a) Find an angle between 0° and 360° that is coterminal with 1170°.1971(b) Find an angle between 0 and 2n that is coterminal with10

Answer 1

Given the angle 1170

We need to find the coterminal angle to the given angle

We will subtract 360 or a multiple of 360 from the given till we reach in the range 0 and 360

So, the coterminal angle =

`1170-3\cdot360=90`

So, the answer will be the coterminal angle = 90
