Answer:

Part a) The measure of the missing angle is \(90\°\)

Part b) The triangle of the figure is a right triangle

Part c) The triangle of the figure is a scalene triangle

Step-by-step explanation:

we know that

The sum of the interior angles of a triangle is equal to \(180\°\)

so

Let

x------> the missing angle

we know that

\(x\°+50\°+40\°=180\°\)

solve for x

\(x=180\°-90\°=90\°\)

The triangle of the figure is a right triangle --------> by its angles

Because the triangle has an angle measure of \(90\°\)

The triangle of the figure is a scalene triangle --------> by its sides

Because the three angles and the three sides measures are different
