Pre-calculus/trig Homework help.?
I need help setting up these question(drawing the triangles).
A rocket tracking station has two telescopes A and B, placed 2.4 miles apart.
The telescopes lock onto a rocket and transmit their angles of elevation to a computer.
What is the distance to the rocket from telescope B at the moment
when both tracking stations are directly east of the rocket,
and telescope A reports an angle of elevation of 20°
and telescope B reports an angle of elevation of 60° ?

From the edge of a 1000-foot cliff, the angles of depression to two cars in the valley below are 21 degrees and 28 degrees. How far apart are the cars?

Tough to draw here; on the telescope one the triangle has a 20 and a (180 - 60) = 120º angle at the base making a 40º at the top, and between the 20 and 120 is 2.4
the cliff one, the triangle has a 21 and a (180 - 28) = 152 making the top be 7
the flagpole makes a 100º angle with the slope so the triangle has 100, 36, and 44º

Out of the three, it is the way it is going, least complicated to toughest. a million. Stats (guy or woman-friendly, as long as you'll be able to desire to earnings graphs and stuff) 2. Trig (you concentration on in specific one undertaking, it is exceptionally guy or woman-friendly) 3. Precalc is genuinely better constructive good than trig. it is larger good than calculus, too. In precalc, you learn a ultimate type of stuff which prepares you for calculus (it is why it is larger good than calculus, with the help of very reality with the help of utilising skill of the time you get there, you recognize each and each and each and each element already). that's what optimal persons say. i've got have been given have been given taken all, and that i could desire to desire to agree, too. i could desire to bypass with trig.

To start off draw a picture of it. It may seem like its a waste but it will help you understand so much better.
