The bridge

Across the circle, the lake passes through its center bridge over the lake. At three different locations on the lakeshore are three fishermen, A, B, and C. Which of the fishermen see the bridge from the largest angle?

Correct answer:

α =  90 °
β =  90 °
γ =  90 °

Step-by-step explanation:

$$\begin{gathered} \alpha =\beta =\gamma \\ \alpha =90=90^{\circ } \end{gathered}$$

$\beta =90=90^{\circ }$

$\gamma =90=90^{\circ }$
