Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AD =4, BD =6, what is the length of DC

Lostsunrise [7]

Answer:

$AC=5$

Step-by-step explanation:

From the question we are told that:

Dimensions

$AD=4\\BD=6$

Generally the equation for these similar right triangle is mathematically given by

$\frac{AC}{AB}=\frac{AB}{AD}=\frac{BC}{BD}$

$\frac{AC}{AB}=\frac{AB}{AD}$

Where

$AD=x$

$AC=x+4$

Therefore

$AB^2=x(x+4)$

Generally the Pythagoras equation for $\triangle$ ADB is mathematically given by

$AB^2=BD^2+AD^2$

$x(x+4)=4+x^2$

$x(x+4)-(4+x^2)=0$

$x^2+4x)-(4+x^2)=0$

$4x-4=0$

$x=1$

Therefore

$AC=x+4$

$AC=1+4$

$AC=5$

Strictly speacking, since 'c' is defined in the statement this shoudl work:

Part 1) According to the exercise, the letter 'c' represents the total cost of the three pounds of oranges. So c is the total cost of the three pounds of oranges.

Part 2) Rami has three pounds of oranges. In order to know how much a pound of oranges cost, he will have to divide by 3 the total cost of the three pounds 'c'

Part 3) The cost per pound is:

cost 1 pound of oranges = c/3
