Answer:
x ≈ 3.1 ft
Step-by-step explanation:
The segment from the centre to the chord is a perpendicular bisector, thus
The triangle is right with base = 
x
Applying Pythagoras' identity to the right triangle, then
( x )² + 1.4² = 2.1²
x² + 1.96 = 4.41 ( subtract 1.96 from both sides )
x² = 2.45 ( multiply both sides by 4 )
x² = 9.8 ( take the square root of both sides )
x = 
≈ 3.1 ft ( to the nearest tenth )
235.24 + 45.58 = 280.82
280.82/2 = 140.41
each check was for $140.41
You do £68.85 - £15.30= (the answer)
Then you do the answer of that divided by 0.85
Answer:
