Question

x = 65 sides: angles: equation:

Explanation:

Step1: Recall angle - sum property of a triangle

The sum of the interior angles of a triangle is 180°.

Step2: Set up the equation

Let the three angles of the triangle be \(x\), 48°, and 70°. The equation is \(x + 48+70 = 180\).

Step3: Solve the equation for \(x\)

First, simplify the left - hand side: \(x+118 = 180\). Then, subtract 118 from both sides: \(x=180 - 118\). So, \(x = 62\).

Answer:

Equation: \(x + 48+70=180\)
Angles: \(x = 62^{\circ}\), 48°, 70°
Sides: Information about sides is not provided by the angle - sum property used here.
