How do you find lengths of sides of isosceles triangle if vertex angle is 15 degrees?

You require another piece of information. Knowing the "vertex" angle will not tell you the length of any one side. You can have a triangle the size of the continental USA with a "vertex" angle of 15 degrees and you can have a triangle invisible to the human eye with a "vertex" angle of 15 degrees. You can see how these would have different side lengths.

What is the measure of the base angles of an isosceles triangle whose vertex angle has a measure of 50 degrees?
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.
The vertex angle of an isosceles triangle is twice as large as one of the base angles Find the measure of the vertex angle?
90 degrees. This is an isosceles right triangle, standing on its hypotenuse.
A base angle of an isosceles triangle is 6 degrees more than the vertex angle. Find the vertex angle?
56 degrees
What is the measure of the base angle of an isosceles triangle if the vertex measures 38 degrees?
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
What is the measurement of the vertex angle of an isosceles triangle is the measure of one of its base angle is 42?
The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.
What is the measure of the base angles of an isosceles triangle whose vertex angle has a measure of 50 degrees?
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.
What is the maximum vertex angle in an isosceles triangle?
an isosceles triangle can have any vertex angle less than 180 and greater than 0, as long the other two angles are equal. an isosceles triangle with a vertex of 179 degrees would just have the other two angles be 0.5 degrees. A right triangle with matching angles (both 45 degrees) would be both a right triangle and isosceles triangle.
The vertex angle of an isosceles triangle is twice as large as one of the base angles Find the measure of the vertex angle?
90 degrees. This is an isosceles right triangle, standing on its hypotenuse.
A base angle of an isosceles triangle is 6 degrees more than the vertex angle. Find the vertex angle?
56 degrees
What is the measure of the base angle of an isosceles triangle if the vertex measures 38 degrees?
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
What is the measure of the vertex angle of an isosceles triangle if one of its base angles measures 53?
If your "53" is in degrees, then the vertex angle is 74 degrees.
What is the measurement of the vertex angle of an isosceles triangle is the measure of one of its base angle is 42?
The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.
The exterior angle of a base angle in an isosceles triangle is 100 degrees What is the measure of the vertex angle?
20 degrees
What is the measure of an acute base angle of the trapezoid of an isosceles triangle vertex of 46 degrees?
For an isosceles triangle with vertex 46 degrees, the sum of the remaining two base angles is 180-46 = 134 degrees. Base angles are equal because it's isosceles, so each angle is half of their sum. 134/2 = 67 degrees. Thus, any isosceles trapezoid formed inside that isosceles triangle by drawing parallel lines to the triangle's base, will have base angle measures of 67 degrees, which are triangle's base angles.
If a base of an isosceles triangle is 75 degrees What is the measure of the vertex angle?
30o
What is the measure of a base angle of an isosceles triangle if its vertex angle measures 65?
57.5 degrees
What is the measure of the vertex angle of an isosceles triangle if the measure of one of it's base angles is 56?
If that '56' has units of 'degrees', then the vertex angle is 68 degrees.
