Question

find the value of x.
(there is a triangle with two angles 50° and 75°, and the third angle is x°)

Explanation:

Step1: Recall triangle angle sum

The sum of angles in a triangle is $180^\circ$.

Step2: Set up the equation

$x + 70^\circ + 75^\circ = 180^\circ$

Step3: Calculate sum of known angles

$70 + 75 = 145$

Step4: Solve for $x$

$x = 180 - 145$

Answer:

$35$
