Question

two angles in a triangle measure (2.3×+25)° and (5.8×+11)°. what is the value of x if the angles are congruent to one another?

Answer 1

If the angles are congruent to one another, we can conclude:

$\begin{gathered} (2.3x+25)=(5.8x+11) \\ \end{gathered}$

solving for x:

$\begin{gathered} 25-11=5.8x-2.3x \\ 14=3.5x \\ x=\frac{14}{3.5} \\ x=4 \end{gathered}$
