Distance after 1 minute = speed * time = 275 * 60 = 16,500 feet
Let the altitude of the plane be y, then
sin 18 = y/16500
y = 16500 sin 18 = 5,098.78 feet

How many triangles can be constructed with angles measuring 50º, 90º, and 40º?
NeX [460]

Answer: Infinite


Step-by-step explanation:

We know that in a triangle the sum of all the interior angles must be 180°.

The given angles 50º, 90º and 40º

The sum of the angles 50º+ 90º + 40º= 180°

Thus, a triangle is possible with the given measurement.,

Let there is another triangle with the given angles, then by AAA similarity criteria they are similar.

Similarly, all the triangles with the same measurements of the angles must be similar.

Therefore, there are infinite number of triangles can be possible with angles measuring 50º, 90º, and 40º.

X + 35/17 = 4 The answer is 33/17 but I got it wrong because I multiplied 4 by 17. Why do I minus 35/17 from 4 instead of multip
Tema [17]

X=33/17

Here is how it works

By the way what you are working with is called improper factions, which is when the big number is placed over the smaller number.

Now 33/17 is also 1 16/17

35/17 is also 2 1/17

Now we can the proper fractions which are 1 16/17 and 2 1/17

1+2=3 and 16/17 + 1/17 equals 1

3+1=4

I enjoyed solving your problem. please vote my answer brainliest..thanks
