Answer:

∠
°
Step-by-step explanation:



- The cosine of an angle is equal to the side adjacent to the angle over the hypotenuse, the longest side.

- We need to find the hypotenuse of this triangle. This is relativly easy to do with a right triangle; we can just use the Pythagorean Theorem.
- Pythagorean Theorem:
where
,
, and
are the 3 different sides of a right triangle.

- Our hypotenuse is
. Now we can finish solving for ∠
.

∠
°
3x = -212
x = 70.66667
And this is assuming it equals to zero.
Discount = 365*30/100 = $109.5
sales price = 365*70/100 = $255.5
