Question

find the value of x. figure is not to scale. x = ° question help: video written example

Explanation:

Step1: Recall angle - sum property of a triangle

The sum of the interior angles of a triangle is 180°. So, we have the equation $x + 43+105=180$.

Step2: Simplify the left - hand side of the equation

$x+(43 + 105)=x + 148$. So the equation becomes $x+148 = 180$.

Step3: Solve for x

Subtract 148 from both sides of the equation: $x=180 - 148$.
$x = 32$.

Answer:

32
