The value of x is 84°.
Solution:
Measure of intercepted arc = 168°
Measure of angle x = ?
<u>Tangent-chord relationship:</u>
<em>If a tangent and a chord intersect at a point, then the measure of each angle formed is half of the measure of its intercepted arc.</em>


The value of x is 84°.
The algebraic expressions can be written as

The given expression is,
Y = log3 27
27 = 3^x
3^3 = 27
so x = 3
