Question

Suppose a triangle has an angle γ, that another angle, say β, in the triangle is three times larger than γ, and that the third angle ρ is 10 degrees less than γ. What is the measure of γ, β and ρ?

Answer 1

\[\begin{array}{rcl}
\gamma +\beta +\rho &=& 180^\circ\\
3\gamma &=& \beta \\
\rho &=& \gamma - 10^\circ
\end{array}\]
