If you place a 20ft ladder 4ft from the base of the wall, what is the angle measure of the ladder to the ground to the nearest d

artcher [175]

Given:

Length of the ladder = 20 ft

Distance between base of the ladder and wall = 4 ft

To find:

The angle measure of the ladder to the ground to the nearest degree.

Solution:

Ladder is the hypotenuse of a right triangle. Here, we have,

Hypotenuse = 20 ft

Base = 4 ft

In a right angle triangle,

$\cos \theta=\dfrac{Base}{Hypotenuse}$

$\cos \theta=\dfrac{4}{20}$

$\cos \theta=\dfrac{1}{5}$

Taking cos inverse on both sides, we get

$\theta=\cos^{-1}\dfrac{1}{5}$

$\theta=78.46304^\circ$

$\theta\approx 78^\circ$

Therefore, the correct option is A.

What is the distance between the lines y = 2x and y = 2x+5? Round your answer to the nearest tenth.

Ilia_Sergeevich [38]

The distance between both lines is 2.24 units

Step-by-step explanation:

There is no straight method to find the distance between two lines. The distance can be found out by finding a point on one line and then finding the distance of that point from the other line. The y-coordinate of point is obtained by putting any value of x in equation . The x and y combined give us the point.

Given

$y=2x\\Putting\ x=1\\y=2(1)\\y=2\\So, the\ point\ on\ y=2x\ is\ (1,2)$

We have to find the distance of this point from y=2x+5

$y=2x+5\\Subtracting\ y\ from\ both\ sides\\y-y=2x+5-y\\2x-y+5=0$

The formula for finding distance of a point (x,y) from a line is:

$d=\frac{|Ax+By+C|}{\sqrt{A^2+B^2}}$

A=2

B=-1

C=5

Putting the values in the formula

$d=\frac{|(2)(1)+(-1)(2)+5|}{\sqrt{(2)^2+(-1)^2}}\\d=\frac{|2-2+5|}{\sqrt{4+1}}\\d=\frac{|5|}{\sqrt{5}}\\d=\frac{5}{\sqrt{5}}\\d=2.236\ units$

Rounding off will give: 2.24 units

The distance between both lines is 2.24 units
