Question

7 directions - create an equation and solve for x for the diagram: triangle sum equation = x = degrees

Explanation:

Step1: Recall angle - sum property

The sum of interior angles of a triangle is 180 degrees. So the equation is $x + 63+61=180$.

Step2: Simplify the left - hand side

$x+(63 + 61)=x + 124$. So the equation becomes $x+124 = 180$.

Step3: Solve for x

Subtract 124 from both sides of the equation: $x=180 - 124$.
$x = 56$.

Answer:

Triangle sum equation = $x + 63+61=180$
$x = 56$ degrees
