Question 1059245: The questions says the ratio of the measure of the vertex angle to the base angle of an isosceles triangle is 8:5. Find the measure of the vertex angle. How am I suppose to find the vertex angle.

Ratio; Isosceles; the description should be clear.
VERTEX to BASE,
8:5
How many base-angles? Two, because isosceles triangle will have two angles of equal measure and one angle of different measure.
What else do you know?
Sum of the interior angle measures is 180 degrees.

Are you still stuck?
If so, maybe you need to say the vertex angle is some product with a factor of some variable, p.
Vertex angle measure is some 8p and you expect ratio of vertex to base is ;
and you also expect .

You are only about two or three simple steps away from finding measure of the vertex angle.
