An airplane takes off and travels 56 ground miles to achieve an altitude of 12.6 miles. What is the angle of elevation of the airplane's path?

≈ 15.5085

Step-by-step explanation:

√6 ≈ 2.45

6 is not a perfect square so its square root is irrational, therefore the decimal form can only be estimated.

√10 ≈ 3.16

The square root of 10 is a single number. That number is irrational, which means that its decimal expansion goes on forever without repeating, and cannot be expressed as a fraction.

√15 ≈ 3.17

This is not simplifiable. But this is approximately what equalled.

2.45(3.16 + 3.17)

= 15.5085
