The altitude is the mean proportional between the left and right parts of the hyptenuse
20/m = m/8
m² = 20 · 8
m² = 160
m = √160
m = 4√10
We can see a right triangle here.
Diagonal is a hypotenuse of the right triangle. Two legs are equal 102 yards each.
We can use Pythagorean theorem
hypotenuse² = leg² + leg² = 2leg²
hypotenuse² = 2leg²
√hypotenuse² = √(2leg²)
hypotenuse = leg*√2
hypotenuse = 102*√2≈144.25 yards
the diagonal ≈144.25 yards

Step-by-step explanation:
Answer:
30.6452% decrease.
Step-by-step explanation:
%
100-69.354 ≈ 30.6452%
The answer would be £20, you would turn this into a proportion and doing that you'd have 70/100=14/x(x being the full cost) then you cross multiply and doing so you get 1400=70x and 1400 divided by 70 equals 20, so your answer is £20
