Answer:
x = 6
Step-by-step explanation:
The segment from O to the chord is a perpendicular bisector.
The triangle formed is right with legs x and 8 and hypotenuse 10
Using Pythagoras' identity in the right triangle, then
x² + 8² = 10²
x² + 64 = 100 ( subtract 64 from both sides )
x² = 36 ( take the square root of both sides )
x = = 6
Answer:
Step-by-step explanation:
diameter = 20
radius = 10 units
Length of Chord = 16 units
The perpendicular from the center to a chord, bisect the chord.
So, base = 16/2 = 8units
Use Pythagorean theorem.
x² + 8² = 10²
x² + 64 = 100
x² = 100 -64
x² = 36
x = √36 = √6*6
x = 6 units

Step-by-step explanation:
1 mile is made up of 1760 yards.
If the library is 5 miles from the post office then the library is (5 x 1760) yards from the post office.
5 x 1760 = 8800
So the library is 8800 yards from the post office.
