Part A: 1. X=$5-10%x
2. $5-5%+5%
Part B: 90%-$5x
part c: Part B would save you more money, for example, if you were paying $25 then if you took off 10% of that that would equal $22.5. Then you subtract five dollars and the answer is 17.5 dollars, which if you do it the other way around it would equal $18.
Answer:A right triangle or right-angled triangle is a triangle in which one angle is a right angle (that is, a 90-degree angle). The side opposite the right angle is called the hypotenuse (side c in the figure).
Step-by-step explanation: hopefully this helps u!
Answer:
2nd option
Step-by-step explanation:
If AB is a tangent to the circle then ∠ B is right angle
Using the converse of Pythagoras' identity.
If the square of the longest side is equal to the sum of the squares on the other 2 sides, then the triangle is right
longest side = 52 and 52² = 2704
48² + (10 + 10)² = 48² + 20² = 2304 + 400 = 2704
Then AB is a tangent to the circle since ∠ B is a right angle
