Find the

Find the third interior angle of the triangle ABC where: α = 48°, γ = 65°.

Correct answer:

β =  67 °

Step-by-step explanation:

$$\begin{gathered} \alpha =48\text{ ° } \\ \gamma =65\text{ ° } \\ \alpha +\beta +\gamma =180\mathrm{°} \\ \beta =180-\alpha -\gamma =180-48-65=67\text{°} \end{gathered}$$
