Answer:
11.2
Step-by-step explanation:
x is the length of a radius of the circle, all radii have the same length.
the chord of length 20 is perpendicular to the segment of length 5, so the segment bisects the chord , so half of the chord is length 10.
The segment of length 10 is one leg of a right triangle while the segment of length 5 is the other leg. The hypotenuse is also a radius of the circle.
The length of the hypotenuse can be found by they Pythagorean Theorem, a^2 + b^2 = c^2, so
5^2 + 10^2 = c^2 or
25 + 100 = c^2 or
c^2 = 125 or
c = = ≈ 11.2
so if one radius is approximately 11.2, then all radii (including the one of length x) are 11.2
Answer:
112.2ft
Step-by-step explanation:
As can be seen in the attached diagram, The top of the building is at C.
The distance from the man to the building is |BD| and the height of the man is |AB| where his eye level is at B.
We are required to find the height |CE| of the building.
Now |AB|=|DE|, (opposite sides of a rectangle).
Tan 65° = |CD|/59
|CD|=59 XTan65°=107.23
The height of the building |CE|=|CD|+|DE|=107.23+5=112.23ft
The height=112.2ft ( to the nearest tenth)
Answer:
it isn't proportional because it doesn't go through the origin.
Step-by-step explanation:
43+t or t+43 more than gives you the clue to add
Only one, if you want to know the measurement of the other side use the cosine law and to know the other angles use the sine law :)
