You use the Pitagora formula:
CD^2+BD^2= (6x-10)^2
CD^2+AD^2=16x^2
AD^2-BD^2=16x^2-(36x^2-120x+100)
0=-20x^2+120x-100
x^2-6x+5=0
x^2-x-5x+5=0
x(x-1)-5(x-1)=0
(x-1)(x-5)=0
x1=1 but if x=1 it means that BC=-4 which cannot be possible
x2=5 so x=5
The answer to your question is C. I hope that this is the answer that you were looking for and it has helped you.
150 minutes. (15,000/2)=7,500 which is 1/2 of the pool. If it fills 50 gallons per minute you’ll want to divide that by 50;(7,500/50) which equals 150
the answer is 150. 150 is the least common multiple of 150, and 150 is a multiple of 5.
One example when you have to draw a diagram to solve an angle measurement problem is triangles looking at the angles and sides
r° = 158°
s° = 180° - r° = 180° - 158° = 22°
