Answer:

50x

Step-by-step explanation:

Lets start!

5(3x + 7) = 20 – 2(x + 1)

So as we should know we have 'PEMDAS' standing for parenthesis, exponents, multiplication, division, and subtraction. You do math (any math) in the order of PEMDAS.

So lets start out with the parenthesis:

(3x +7) is 10x and (x +1) is 1x

now lets multiply:

So now we have that the equation is

5 · 10x · 1x

5 · 10x is 50x and 50 · 1x is 50x

Therefore our answer is 50x.

Hope this helped have a fantastic day! (✿◡‿◡)

When flying at an altitude of 5 miles, the lines of sight to the horizon looking north and south make about a 173.7 degree angle

oksian1 [2.3K]

5 miles high is one of the sides of a triangle depending on accuracy level
h^2=x^2+y^2
we don't have 2 distances
Tan A=O/a
O=a tan A
We solve for O because the angle is at the top of the line going up and we want the opposite angle that is along the ground
O=5×tan(173.7/2)=90.854033512
The distance he can see is:
90.85*2~181.7 miles

Now we need to find the distance between lines:
The north south distance between each line is 69 miles
thus the number of degrees he will see will be:
181.7/69
=2 19/30
