Question

what is the value of x? (with a right - angled triangle image, one angle is 50° and another angle is x°)

Explanation:

Step1: Recall triangle angle sum

A triangle's angles sum to \(180^\circ\). This is a right triangle, so one angle is \(90^\circ\), another is \(50^\circ\), and we need to find \(x\).

Step2: Set up the equation

The sum of the angles in a triangle is \(180^\circ\). So, \(x + 90^\circ + 50^\circ = 180^\circ\).

Step3: Solve for \(x\)

First, add \(90^\circ\) and \(50^\circ\): \(90^\circ + 50^\circ = 140^\circ\). Then, subtract this from \(180^\circ\): \(x = 180^\circ - 140^\circ = 40^\circ\).

Answer:

\(x = 40^\circ\)
