Question

Find the value of n.

Answer 1

n=25

Explanation:

Using the relation that describes the measure of the angle formed by two secants being equal to half of the difference of the 2 arcs (large arc-small arc) we can establish the relation;

`10 = (45 - n)/(2)`

`20 = 45 - n`

`- 45 + 20 = - n`

`- 25 = - n`

`n = 25`
