Explanation:

Step1: Use the property of right - angled triangle

In the right - angled triangle, we know that the sum of angles in a triangle is \(180^{\circ}\). For the right - angled triangle with one angle \(70^{\circ}\) and the right angle \(90^{\circ}\), we can find \(X\) using the formula \(X + 70^{\circ}+90^{\circ}=180^{\circ}\).

Step2: Solve for \(X\)
