It is important to remember that a discount is the same as a decrease and a sales tax means an increase. If you remember this, you will easily know how to go about solving the mathematical questions.
A 15% discount is similar to a 15% decrease because a discount means a decrease in price and serves the purpose of a decrease.
An 8% sales tax is like an increase because it means that it is an 8% increase over the original price.

Find the measure of the exterior angle. ILL GIVE BRAINILEST

USPshnik [31]

Answer:

108°

Step-by-step explanation:

In order to find the measure of the exterior angle, we first need to solve for a. We know that the sum of a triangles' angles is always 180°.

Now we set up an equation:

180 = 44 + (a + 10) + (180 - 2a)

180 = 44 + a + 10 + 180 - 2a

180 = -a + 234

-54 = -a

54 = a

Because we know that a = 54, we can now solve for the exterior angle:

2(54) = 108

Therefore, the measure of the exterior angle is 108°.
