$\large \sf{✟ \: Problem \: ✟} :$

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°.

Which statements are true regarding the diagram?

Murrr4er [49]

As <GNJ & < JNK form a striaght angle

And < JNK = 90°

So <GNJ = 90°

So <GNH + <HNJ = 90°

So GNH & HNJ are complimentary is true.

As JNK and KNL do not form a straight angle.

So <JNK +< KNL is not equal to 180°.

Hence JNK and KNL are supplementary is not true.

As <KNM & < JNK form a straight angle

And < JNK = 90°

So <KNM = 90°

So <KNL + <LNM = 90°

So KNL & LNM are complimentary is true.

As HNL makes a straight angle

And so

mHNK + mKNL = 180° is true

As MNG itself is 90°

<MNG + <GNH cannot be 90° hence this is false.

Irina18 [472]

Answer:

There are 1240 students who attended Washington Middle School.

Step-by-step explanation:

Given:

Students who attend Washington Middle School are either in seventh or eighth grade.

At the end of the first semester 25% of the students at Washington Middle School were on the honor roll.

Seventh graders represented 60% of the students on the honor roll.

If 124 students on the honor roll were in eighth grade.

Now, to find the students attend Washington Middle School.

Let the total number of students be $x.$

So, the students at Washington Middle School were on the honor roll:

25% of $x$

$=\frac{25}{100} \times x$

$=\frac{25x}{100}$

$=\frac{x}{4}$

As, given seventh graders represented 60% of the students.

So, the students on the honor roll represented as seventh graders:

$60\%\ of\ \frac{x}{4}$

$=\frac{60}{100} \times \frac{x}{4}$

$=0.6\times \frac{x}{4}$

$=\frac{0.6x}{4}$

As, 124 students on the honor roll were in eighth graders.

Thus,

According to question:

$\frac{x}{4} -\frac{0.6x}{4} =124$

$\frac{x-0.6x}{4} =124$

$\frac{0.4x}{4} =124$

Multiplying both sides by 4 we get:

$0.4x=496$

Dividing both sides by 0.4 we get:

$x=1240.$

Therefore, there are 1240 students who attended Washington Middle School.

Answer: It's the first 3, not the last one

Step-by-step explanation:

Confusing! But if the planes have two points in common, they intersect.

The last choice is the top and bottom. They have no edges in common, so they don't intersect
