Answer:
7 ft.
Step-by-step explanation:
Please see the attached image.
I named the center Z btw
Because the circle is split into three congruent angles, each angle is 360/3=120°.
After dropping an altitude on the bottom triangle, the angle is bisected, so 120/2=60°.
By dropping the altitude, we also created a 30-60-90 triangle. By now you have probably learned the proportions for the sides of a 30-60-90 triangle, but if you haven't,
the side opposite the 30° angle is half the hypotenuse, and the side opposite the 60° angle is the other leg multiplied by √3.
So ZW is 4/2=2, and WY is 2√3.
XW=WY, so XY=2√3*2=4√3
4√3 is approximately 7.
7 ft.
Answer:
The answer is number 3 Because it is supposed to divide the number
Answer: =4xy(2z−3)
Step-by-step explanation: Factor ((−12x)(y))(z)−12xy+20xyz
8xyz−12xy
Answer:
See below.
Step-by-step explanation:
a. 973 * 80
= 973 * 8 * 10
= 7784 * 10
= 77,840.
b. 56 * 2000
= 2*56 * 1000
= 112,000.
c. 5.7 * 300
= 5.7 * 3 * 100
= 17.1 * 100
= 1710.
d. 0.46 * 50
= (0.46 * 100) / 2
= 46 / 2
= 23.
I dont understand what you mean which question?
