Question

Please help me with this

Answer 1

Answer:

$x = \sqrt{11.4^2+2.6^2}$

Rounded to the nearest hundredths: 11.69.

Step-by-step explanation:

I would use the Pythagorean theorem for this problem.

The difference between the highest point and the lowest point of AD is 9.8-7.2 = 2.6, so that would be the height of the triangle. The length/base of the triangle would be 11.4.

Now, just solve using Pythagorean's theorem:

$x = \sqrt{11.4^2+2.6^2}$

Rounded to the nearest hundredths: 11.69.

I hope this helped you.
