Mathematics
1 answer:
kompoz [17]3 years ago
3 0

Answer:

\huge\boxed{m\angle 1 = 131 \textdegree}

\huge\boxed{m\angle 2 = 49 \textdegree}

\huge\boxed{m\angle 3 = 112 \textdegree}

Step-by-step explanation:

We can use basic angle relationships to find the measure of angles 1, 2, and 3 here.

First off, we know that the 49° angle and m∠1 are supplementary. This means that their angle measures will add up to 180°.

Since we know one, we can find the other easily.

x + 49 = 180\\\\x = 180-49\\\\x = 131

So m∠1 = 131°.

We also know that m∠2 is opposite to the 49° angle. This means that m∠2 is also 49°.

Now, we know that m∠3 is also opposite to the 112° angle. Therefore, their angle measures are the same, and m∠3 is also 112°.

Hope this helped!

Find the slope of the line that passes through (10,8) and (1,9).
lesya [120]

Answer:

-\frac{1}{9}

Step-by-step explanation:

between (1, 9) and (10, 8), the x moves by 9 and y moves by -1

The slope is equal to: \frac{\Delta y}{\Delta x} = \frac{-1}{9} = -\frac{1}{9}

Dhaulagiri is the 7th highest mountain in the world. Ms. Fink is walking through
11111nata11111 [884]

Answer:

4833 m

Step-by-step explanation:

Given that her angle of elevation at the first recording is 47.3 at an altitude of 4900 m

We use Pythagoras Theorem to get this done

We can say that the opposite of the angle is the altitude, while the hypotenuse of the triangle, is the distance between herself and the top

Using the sine angle rule, we have

Sine 47.3 = 4900 / h

h = 4900 / sin 47.3

h = 4900 / 0.7349

h = 6668 m

This means that she was 6668 m away from the top of the mountain

She then moves 1000 m closer to the mountain top, this means that our h = 6668 - 1000

Using the same sine angle rule, we have

Sine 58.5 = o / 5668

o = 5668 * sine 58.5

o = 5668 * 0.8526

o = 4833 m

She is 4833 m above the sea level
