3x - 2 = x + 1
2x = 3
x = 3/2
x = 1.5

3x - 2 = 3(1.5) - 2 = 2.5
or
x + 1 = 1.5 + 1 = 2.5

P = 4(2.5) = 10

perimeter of square is 10 cm so side of square = 2.5cm

This is area right???
taurus [48]

Answer:

Yes

Step-by-step explanation:

So permiter is two*lengths plus 2*width of a shape.

Area is the length times the width.

A pilot can see the runway she is about to land on directly ahead. When looking at each end of the runway, the angles of depress
Lostsunrise [7]
First, we get the length of the runway in which the pilot had seen a 45° by using the trigonometric formula of tangent. 
                                    tan 45° = 1,500 / x
The value of x from the equation is 1500 ft. 
We do the same for the 42°
                                   tan 42° = 1,500 / y
The value of y is equal to 1665.92 ft. To determine the length of the runway, we subtract the lengths calculated and this will give us an answer of 165.92 ft.
