Question

find the value of x.

enter the correct number in the box.
show hints
x = \square

Explanation:

Step1: Use the exterior - angle property of a triangle

The exterior - angle property of a triangle states that an exterior angle of a triangle is equal to the sum of the two non - adjacent interior angles. Let's assume the triangle has an exterior angle \(x\) and two non - adjacent interior angles \(25^{\circ}\) and \(30^{\circ}\).

Step2: Calculate the value of \(x\)

By the exterior - angle property, \(x=25 + 30\).

Answer:

\(55\)
