Question

what is $mwidehat{uv}$?
$95^circ$
$130^circ$
$mwidehat{uv} = \square ^\circ$
submit

Explanation:

Step1: Sum of circle's arcs is 360°

The total measure of all arcs in a circle is $360^\circ$. Let $m\widehat{UV} = x$.

Step2: Set up the equation

$x + 95^\circ + 130^\circ = 360^\circ$

Step3: Calculate the sum of known arcs

$95^\circ + 130^\circ = 225^\circ$

Step4: Solve for $x$

$x = 360^\circ - 225^\circ$

Answer:

$135^\circ$
