The length of the base angle is triangle

Answer:

70 degrees

Step-by-step explanation:

since an isosceles triangle is symmetrical, i cut the triangle in half (vertically) so that it became a right triangle. so the angle sides are now 20 degrees at the top, 90 degrees (right angle, where it was cut), and x degrees. 20 + 90 + x = 180 degrees (total amount of degrees in a right triangle) x = 70 degrees.

hope this helps!
