The vertex angle of an isosceles triangle is twice as large as one of the base angles. Find the measure of the vertex angle.
01:09
An isosceles triangle is a triangle in which two sides are equal in length. The angle between the two equal sides is called the vertex angle, while the other two angles are called the base angles. If the vertex angle is $40^{\circ},$ what is the measure of the base angles?

and this one you have in a sausage triangle with base angles X. And you’re trying to find the equation for your vertex angle. So to make it easier, we’re just gonna call that question mark. Three angles of a triangle add up to be 100 and 80 degrees, so X plus X plus question mark. What we’re trying…
