1: Identify the angle.
<em>The following angle is a 90.</em>
2: Set up the equation.
<em>x + (3x + 10) = 90</em>
3: Combine like terms.
<em>4x + 10 = 90</em>
4: Solve for x.
<em>4x + 10 = 90</em>
<em> -10 = - 10</em>
<em>--------------------------</em>
<em>4x = 80</em>
<em>------------------</em>
<em>4 4</em>
<em>x = 20</em>
Your answer is x = 20.
