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 \triangleADB 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

-4.5-4.2(-x-5.5)=3x solve for x​
Mice21 [21]
-4.5 - 4.2(-x - 5.5) = 3x
-4.5 + 4.2x + 23.1 = 3x
18.6 + 4.2x = 3x
subtract 4.2x from both sides of the equation
18.6 = -1.2x
divide -1.2 from both sides of the equation
-15.5 = x
