Question

there is a right triangle, one of the acute angles is 40 degrees, and the other acute angle (marked with?) needs to be found.

Explanation:

Step1: Recall triangle angle sum

A right triangle has one \(90^\circ\) angle, and the sum of angles in a triangle is \(180^\circ\).

Step2: Calculate the unknown angle

Let the unknown angle be \(x\). Then \(90^\circ + 40^\circ + x = 180^\circ\). Solving for \(x\), we get \(x = 180^\circ - 90^\circ - 40^\circ = 50^\circ\).

Answer:

\(50^\circ\)
