\large \sf{✟ \: Problem \: ✟} :

An airplane is flying at a height of 5 kilometers above the ground. The distance along the ground from the airplane to the airport is 7 kilometers. What is the angle of depression from the airplane to the airport? (Write the answer to the nearest degree.)

\rule{70mm}{2.9pt}

\large \sf{✟ \: Solution \: ✟} :

✞ Step 1 ✞: Identify what is asked in the problem.

❒ The angle of depression from the airplane to the airport.

✞ Step 2 ✞: Use appropriate trigonometric ratio to solve the problem.

❒ Since the two legs of the right triangle are part of the problem, hence we use tangent ratio:

\qquad \qquad \bigstar \:  \: \boxed{\tt{ \quad \tan A \degree =  \frac{5}{7}  \quad}}

✞ Step 3 ✞: Solution and interpretation.

:  \qquad \large \implies \tt{ \tan A =  \frac{5}{7} }

:  \qquad \large \implies \tt{A =   \tan^{ - 1}(\frac{5}{7} )}

:  \qquad \large \implies \tt{A =  35.54 \approx \pmb{36 \degree}}

\rule{70mm}{2.9pt}

\large \sf{✟ \: Answer \: ✟} :

Hence, the angle of depression from the airplane to the airport is approximately 36°.

A 16 foot ladder is leaning up against the wall. If the bottom of the latter is 6 feet from the base of the wall, how far up the
PSYCHO15rus [73]
For this question, you must use the Pythagorean theorem.
a^2 + b^2 = c^2

In this situation c=16 and a=6
First do 16^2. This equals 256
Second do 6^2. This equals 36

Now, subtract 36 from 256 and fond the square root.

Your answer should be 14.8

A shark weighs 405 kg and 68 grams a second shark weighs 324 kg and 75 g how much more does the first shark weigh in grams than
mariarad [96]

For this case we have to by definition:

1 kg equals 1000 grams

Shark 1:

405 kg and 68 grams

405 kg * \frac {1000 g} {1kg} = 405,000 grams

Thus, shark 1 weighs 405,068 grams.

Shark 2:

324 kg and 75 grams

324 kg * \frac {1000 g} {1 kg} = 324,000 grams

Thus, shark 2 weighs 324,075 grams.

Subtracting we have:

405.068 grams-324.075 grams = 80.993 grams

Thus, shark 1 weighs 80,993 grams more than the second.

Answer:

Shark 1 weighs 80,993 grams more than the second.
