Answer:

Step-by-step explanation:
As per the problem, the given triangle is a right triangle. This is signified by the box around one of its angles, this box states that the angle it is surrounding is a right angle.
Since it is a right triangle, one can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states that; (
), where (
) and (
) are the legs of the right triangle, or the sides adjacent to the right angle. (
) is the hypotenuse or the side opposite the right angle.
Substitute in the given values and solve, note that (
) represents the unknown leg (side).

Inverse operations,

whatever% of anything is just (whatever/100) * anything.
so the socket set has a 40% off, what is 40% of 36? well, is just (40/100) * 36, or 14.4, that's the discount, so the sale price is 36 - 14.4, or 21.6.
plus the 8.25% taxation, what is 8.25% of 21.6? well, is just (8.25/100) * 21.6, or 1.782.
so the total price is 21.6 + 1.782, or 23.382, or about 23 bucks and 38 cents.
Answer:
The price before tax was $110
Step-by-step explanation:
Here the price paid totals $129.25, including b (the pre-tax price) an 17.5% of b: b + 0.175b = $129.25. Combining the b terms, we get:
1.175b = $129.25. Solving for b by dividing both sides by 1.175, we get
b = $110. The price before tax was $110.
