Answer:
Part a) The measure of the missing angle is [tex]90\°[/tex]
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 [tex]180\°[/tex]
so
Let
x------> the missing angle
we know that
[tex]x\°+50\°+40\°=180\°[/tex]
solve for x
[tex]x=180\°-90\°=90\°[/tex]
The triangle of the figure is a right triangle --------> by its angles
Because the triangle has an angle measure of [tex]90\°[/tex]
The triangle of the figure is a scalene triangle --------> by its sides
Because the three angles and the three sides measures are different
