A pennant is in the shape of an isosceles triangle. One leg of the triangle is fastened to a stick so that the bottom leg of the triangle makes exterior angle with the stick. What is the measure of each remote interior angle?

The question is incomplete. Here is the complete question.

A pennant is in the shape of an isosceles triangle. One leg of the triangle is falstenes to a stick so that the bottom leg of the triangle makes an exterior anlge of 84° with the stock. What is the measure of each remote interior angle?

42°

Step-by-step explanation: An isosceles triangle has two equal sides. Because of that, the base of the triangle has congruent internal angles. The pennant's drawing is in the attachment.

The sum of internal angles of a triangle is 180°.

The external angle added to the internal angle also results in 180°.

So, we can write as:

x + x + 180 - 84 = 180

2x = 180 - 180 + 84

2x = 84

x = 42

Each remote internal angle of the isosceles triangle is 42°
