Therefore, the perimeter of the quadrilateral ABCD is 20 units.
Answer:
Step-by-step explanation:
We have the right triangle. The sum of the angles measured in the right triangle is 90 °. Therefore we have the equation:
<em> add 10 to both sides</em>
<em>divide both sides by 10</em>
The measure of angles:
Put the value of x to the eqpressions:
