Question

In △ABD, altitude AC¯¯¯¯¯ intersects the right angle of triangle ABD at vertex A. BC=3.1 in. and CD=7.2 in..

What is the length of AC¯¯¯¯¯?

Enter your answer in the box. Round your final answer to the nearest hundredth.

Answer 1

4.72

Explanation:

I took the test.

Answer 2

4.72 in.

Explanation:

BC = 3.1 in.

CD = 7.2 in.

Altitude of right triangle altitude is given as
`h = √(xy)`, where:

h = altitude

x = 3.1 in.

y = 7.2 in.

Plug in the values into the formula

`h = √(3.1*7.2)`

`h = √(22.32)`

`h = 4.72 in.` (nearest hundred)
