Question

enter your answers in the boxes to find the value of x.
the sum of the two known angle measures is $\square$°.
$x = 180° - \square$°
$= \square$°

Explanation:

Step1: Sum the known angles

$65^\circ + 90^\circ = 155^\circ$

Step2: Subtract sum from $180^\circ$

$x = 180^\circ - 155^\circ$

Step3: Calculate final value of $x$

$x = 25^\circ$

Answer:

The sum of the two known angle measures is $155^\circ$.
$x = 180^\circ - 155^\circ$
$= 25^\circ$
Final value of $x$: $25^\circ$
