A wall is 15 ft. High and 10 ft. From a house. Find the length of the shortest ladder which will just touch the top of the wall and reach a window 20.5 ft. Above the ground.

Answers

Answer 1

Answer:

the length of the shortest ladder is 11.41 feet

Step-by-step explanation:

The computation of the length of the shortest ladder is shown below:

AB^2 = AC^2 + BC^2

AB^2= (10)^2 + (5.5)^2

AB^2= 100 + 30.25

AB^2 = 130.25

AB = 11.41 feet

hence, the length of the shortest ladder is 11.41 feet

Which of the following could be the equation for this line?

Answers

Answer:

y=13x-8

Step-by-step explanation:

First, find if the slope is positive or negative. The slope is positive because the line goes up and right. This narrows it down to A or C. Then, find if the y-intercept is positive or negative. It is negative because the line intercepts the y-axis below the origin.

What is the equation of the line that passes through the point (-6, -2) and has a
slope of 1/6 ?

Answers

Answer:

y = 1/6x - 1

Step-by-step explanation:

We already know that the slope is 1/6, which will be the m in the equation.

To find the y-intercept, you will have to plug the values of x and y into the equation so far, which is y = 1/6x + b.

-2 = 1/6 (-6) + b

-2 = -1 + b

-1 = b

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

in the picture there is a Hyp and an Opp

so, use the function that has those  sin has those , huh

then,  

sin(Ф) = 12/13

Ф = arcSin(12/13)

Ф = 67.38 °

now we know that angle.. now we can get cos

cos(67.38 °) = adj / 13

13 * cos(67.38 °)  = adj

oh it's exactly

5 = adj

I feel like that's right since it worked out to be exactly 5  :)

Cos(Ф) = 5 / 13

there is  your answer :)
