<h3>What is a proportion?</h3>A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, a 180º angle has a measure of radians. What is the measure of a 540º angle? The <em>rule of three</em> is given by:
180º - rad.
540º - x rad.
Applying cross multiplication:
180x = 540.
x = 540/180 = 3.
The value of a is of 3.

Answer:
x = 10
Step-by-step explanation:
DE is the midsegment joining the midpoints of BC and AC respectively.
Therefore, by the property of midsegment of a triangle,
DE will be parallel and half of the measure of the third side of the triangle.
DE =
5 =
x = 10 units
