Given:
Height of Mountain A = 5210 feet
Distance of Mountain A from a helicopter above the peak = 1000 feet
Angle of depression:
Mountain B to helicopter = 43 degrees
Mountain B to Mountain A = 19 degrees
First, draw an illustration and label the enumerated given values.
Observe that there are two right triangles formed:
From the triangle formed by the helicopter and Mountain B,
let x = total height of mountain B
y = leg of first triangle (helicopter and mountain b)
h = hypotenuse
Use the Pythagorean Theorem:
cos (43) = y / h
From the second triangle formed by mountain b and a,
cos (19) = (1000 + y) / h
solve for h and y
then, solve for the height of Mountain B:
x = 1000 + y + 5210
Answer:
The answer is True.
Step-by-step explanation:
-3x - 10 > -31
-3(5) - 10 > -31
-15 - 10 > -31
-25 > -31
True.
Answer:
2 and 1 because they are directly next to a variable
Answer:
None
Step-by-step explanation:
Let’s graph the points first.
Look at the image below.
And by looking at the image we can tell that none of the points lay on the same horizontal line.
<em>Thus,</em>
<em>none of the points lay on the same horizontal line.</em>

The answer would be .67 or .66666... since it’s infinite; or 2/3 in fraction form
