The measure of one base angle is an isosceles triangle is 20 degree. the measure of the largest angle in the triangle is

140°

Step-by-step explanation:

Every triangles angles when combined equals 180°

In an isosceles triangle there are 2 acute angles and one obtuse angles.

It was given that the base angle/acute angle is 20°

This brings us to our equation. 20° + 20° + x = 180°

20 + 20 = 40

40 + x = 180

Now we solve algebraically:

180-40= 140

Therefore the answer is x = 140°
