Question

determine whether the pair of angles whose mesures are given below are conterminal angles 380,-700​

Answer 1

Step-by-step explanation:

Find the difference between the given two angle measures. 

380° - 20°  =  360°

Step 2 : 

The result of step 1 is

=  360°

=  1(360°)

which is a multiple of 360°. 

So, 380° and 20° are coterminal angles. 

Example 2 : 

Determine the following pairs of angles are coterminal.

40°, 400°
