[tex]\begin{gathered} Let´s\text{ say A, B and C are the angles} \\ \text{Hence} \\ A+B+C=180 \\ \text{But} \\ A=45 \\ \text{and} \\ B=C=\text{ x} \\ \text{Then} \\ 45+x+x=180 \\ 45+2x=180 \\ 2x=180-45 \\ 2x=135 \\ \text{Solving x} \\ x=\frac{135}{2} \\ x=67.5 \\ \text{Therefore} \\ \text{The measure of the other two angles is 67.5} \\ \end{gathered}[/tex]
