How to find degree in a triangle

A triangle 's interior angles typically add up to 180 ° when a triangle 's outer angles are equal to the sum of the two inner angles that are not adjacent to it. Subtracting the angle of the vertex of interest from 180 ° is another way to measure the exterior angle of a triangle.

If we add all three angles in any triangle we get 180 degrees. So, the measure of angle A + angle B + angle C = 180 degrees. This is true for any triangle in the world of geometry. We can use this idea to find the measure of angle(s) where the degree measure is missing or not given.

Step-by-step explanation:

C because the amount of deliveries (6) multiplied by the fee ($4.44) is $26.64 and as you go down the table each answer is correct
whereas with the tables b and d the delivery fee and deliveries made are switched as d is incorrectly shown as $26.64 when it should be f is ...

Therefore the correct answer should be C
