On a compass, due east is a 1/4 turn clockwise from due north. How many degrees are in a 1/4 turn?

vladimir2022 [97]

Answer:

$90^o$

Step-by-step explanation:

We have been given that on a compass, due east is a 1/4 turn clockwise from due north.

Since we know that a compass is in form of a circle and the measure of degrees in a circle is 360 degrees.

To find the number of degrees in a one-fourth turn, we will divide 360 by 4.

$\text{Number of degrees in a 1/4 turn of compass}=\frac{360^o}{4}$

$\text{Number of degrees in a 1/4 turn of compass}=90^o$

Therefore, there are 90 degrees in a 1/4 turn of compass.
