Answer 1

Question:

Solution:

Applying the Pythagorean theorem, we obtain the following equation:

$h\text{ = }\sqrt[]{6^2+9^2}$

this is equivalent to:

$h\text{ = }\sqrt[]{36^{}+81}$

this is equivalent to:

$h\text{ = }\sqrt[]{117\text{ }}=\text{ 10.8}$

so that, we can conclude that the correct answer is:

$10.8$
