Question

an isosceles triangle has base angles that each measure 48°. Which equation can be used to find x, the measure of the third angle of this isosceles triangle in degrees?

Answer 1

Since an isosceles triangle has two equal angles, and in this case the base angles are both 48°, we can use the equation:

x + 48 + 48 = 180

This equation states that the sum of the three angles in any triangle is always 180°. By solving for x, we can find the measure of the third angle of the isosceles triangle.
