Question

a right triangle has one angle that measures 40°, what is the measure of the other acute angle?

Explanation:

Step1: Recall the sum of angles in a triangle

The sum of the interior angles of a triangle is \(180^{\circ}\). In a right - triangle, one angle is \(90^{\circ}\).

Step2: Set up the equation

Let the unknown acute angle be \(x\). We know that \(90^{\circ}+40^{\circ}+x = 180^{\circ}\).

Step3: Solve for \(x\)
