Question

How do you find the missing length of an isosceles triangle given Base = 20 Angle = 25?

Answer 1

Answer:

Use the Pythagorean Theorem to find the base of the right triangle. Now, because two of the angles in this triangle are the same, this is an isosceles triangle. In an isosceles triangle, the sides that are directly across from the congruent angles are also congruent.

Step-by-step explanation:

base =20

angle=25
