Find the base angles.

Each base angle would be 70°.

Step-by-step explanation:

*Base angles means the two equal angles formed on the base are called base angles.

Base means the third unequal side of the triangle. *

Given triangle is isosceles triangle.

The angle of vertex which is given is 40°.

Let each base angle be x.

We know that,

There are two base angles in a isosceles triangle.

And, Sum of angles of triangle is 180° .

Therefore,

Now Solve For x. That would be the solution.

Steps:

Combine like terms:

Subtract 40 from both sides:

Simplify the LHS and RHS:

Divide both sides by 2:

Use cancellation method and cancel LHS and RHS:

Hence, each base angle would be 70°.

Verification:

As we know that sum of angles of triangle is 180°.

So,

We got that one base angles of the given isosceles triangle is 70° and other is 70°, and the vertex angle is 40°[Given].

Solve it.

I hope this helps!

Let me know if you have any questions.
