Find the missing angle measure. then classify the triangle by its angles and by its sides.

iren [92.7K]

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 $180\°$

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

Leokris [45]

Answer:

480 people

Step-by-step explanation:

180 = (x)(0.375)

Solve for x:

180 = (x)(0.375)

480 = x

So, Annette surveyed 480 people
