Question

Triangle A is an isosceles with two angles of measure x degrees and one angle of measure y degrees

write an equation relating x and y

Answer 1

Since triangle A is isosceles, two of its angles are equal in measure. Let's call this common measure x. The remaining angle is y degrees.

The sum of the measures of the angles in a triangle is always 180 degrees.

So, we can write the equation:

x + x + y = 180
