The simplified expression would be 3s + 15.
In order to find this we need to write an equation for the longest side. Since it's 3 more than twice as much as the smallest side (s), we can express it as 2s + 3. Now we simply add all 3 together and simplify.
2s + 3 + 12 + s -----> simplify
3s + 15

Hence, the m∠e is 85.
<h2>What is an angle?</h2>
An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs, and sometimes the arms of the angle. There are many daily life examples of an angle, such as cloth-hangers, arrowheads, scissors, partly opened doors, pyramids, edge of a table, edge of a ruler, etc.
<h3>How to solve?</h3>
∠C + ∠D = 180° (consecutive angles)
7x +11 + 7x + 1 = 180°
14x = 168°
x = 12°
m∠e = 7x + 1
= 7(12°) + 1
= 85°
