Question

In the triangle below, suppose that m2C=(x+3), mZD=(x+3), and mZE= (5x-1)º.Find the degree measure of each angle in the triangle.

Answer 1

`\begin{gathered} \text{The sum of angle is,} \\ C+D+E=180 \\ x+3+x+3+5x-1=180 \\ 7x+5=180 \\ 7x=175 \\ x=25 \end{gathered}`

Now the angle in the degree is,

`\begin{gathered} C\Rightarrow x+3=25+3=28 \\ D\Rightarrow x+3=25+3=28 \\ E\Rightarrow5x-1=5*25-1=124 \end{gathered}`
