Please help. Solve the value of x
​

x = 6

Step-by-step explanation:

GIVEN :-

An isosceles triangle with one side extended.Measure of one base angle = 66°Measure of another base angle = m∠2 = 11x°

TO FIND :-

Value of x

FACTS TO KNOW BEFORE SOLVING :-

An isosceles triangle has 2 equal sides (known as legs) & the third side (known as base).The angle included by the legs is called the vertex angle and the angles that have the base as one of their sides are called the base angles.In an isosceles triangle , base angles are equal in measure.

PROCEDURE :-

As it's an isosceles triangle , it's base angles are equal .

So, m∠2 = 66°

Iwould think that the correct answer is 8.1
