Answer:
Step-by-step explanation:
x has the same value as RT since they are equal sides of the isosceles triangle.
RT is also the hypotenuse of ΔRST - 30°×60°×90° right triangle.
Acoording to the property of such triangles, the ratio of sides is:
We have:
Use the ratio to find the lenght of RT
- 2√3 : RT = √3 : 2
- RT = 2*2√3/√3
- RT = 4
So the value of x is 4 units
Answer:
percentage of interest = 22.6% (to one decimal place)
Step-by-step explanation:
actual price paid (including interest) = 429, out of which
interest = 429-350 = 79
Percentage of interest out of actual price paid
= 79/429* 100%
= 22.6%
20% = 0.20
50 * 0.20 = $10 discount
50 - 10 = 40
The price after 20% discount is $40
