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:
d
Step-by-step explanation:
it keeps going up by 2 and 2x2 is 4 4x2 is 8 so on?
The measure of BD and BC are 7 and 7√2 respectively
<h3>Triangular altitude theorem</h3>
A triangle is a shape with 3 sides and angles.
According to the theorem
CD/BD = BD/DA
From the given figure
CD = DA = 14/2
CD = DA = 7
Substitute
7/BD = BD/7
BD² = 7²
BD² = 49
BD = 7
Determine the measure of BC
sin 45 = BD/BC
sin45 = 7/BC
BC = 7/sin45
BC = 7√2
Hence the measure of BD and BC are 7 and 7√2 respectively

It would be 0.
5 times zero is zero, adding 6 will make it equal to 6.
