Percent error = (estimate - real)/(real) * 100
percent error = (78.25 - 75.50)/(75.50) * 100
percent error = 3.6%
Answer:
x equals 3.00cm
Step-by-step explanation:
Use Pythagoras' Theorem.
a = (14x-45)
b = (16x+27)
c = (25x)
Plug in the variables above into Pythagoras' Theorem that is, a^2+b^2=c^2.
Solve the resulting quadratic equation and reject the negative answer as length is always positive.
The answer will be for every x, y will be 1.25

Population of England in 2003 = 383 * 130,281 = 49,897,623
In 2008 this is 0.84 * 61,000,000 = 51,240,000
Increase = 51,240,000 - 49,897,623 = 1,342,377
Answer is 1,300,000 to 2 significant figures.
