Respuesta :

The expression to find the value of the final angle of the triangle will be 180° - 40° - α.

How to solve the triangle?

Your information is incomplete as the triangle isn't attached. Therefore, an overview will be given.

Firstly, it's important to know that the total angle in a triangle is 180°. A triangle has three sides. In this case, angle B is given as α.

Let's assume that another angle is given as 40°. Therefore, the expression to find the value of the final angle will be 180° - 40° - α
