Question

score : date : le sum n =

Explanation:

Step1: Recall the triangle angle - sum formula

The sum of the interior angles of a triangle is \(180^{\circ}\). So, \(n + 59+54=180\).

Step2: Solve for \(n\)

First, calculate \(59 + 54=113\). Then, \(n=180-(59 + 54)\). Substitute \(59 + 54 = 113\) into the equation, we get \(n=180 - 113\).

Answer:

\(n = 67\)
