This is the last question of my quiz, I need help with it. I need just one question answered.
Question: The angles opposite the congruent sides of an isosceles triangle are congruent. Find the value of x in the triangle. Show all your work.
The triangles' value is 70 degrees.
Isosceles triangles measure around 90 and below, just like acute angles. So, I got my answer by finding the complement of the equation by subtracting 90-70, or 70-90. The complement of the triangle is 20 degrees, so x=20.
Thank you in Advance to whoever answers my question. :)

If 70° is one of the two congruent angles, then the other two angles are 70° and 180-(70+70)=30°
If 70° is the vertex angle, then the other two angles are both (180-70)/2 = 55°
Nothing has been said here about right angles.
