A ladder 5m long rests against a house and makes an angle of 720 with the ground. How far does the ladder reach up the wall?

1 answer:

4 0

Um the angle is 72. No ladder can make an angle of 72. Anyway trigonometry is the only way to solve this.

The function is sin. Sin(72)= opposite/5(hypotenuse)
5sin(72)=4.76 metres to 2 decimal places

Find the slope of the line that contains these points.(5,1) (-3,1)

shtirl [24]

Slope equals change in y divided by change in x.

m=(y2-y1)/(x2-x1)

m=(1-1)/(5--3)

m=0/8

m=0

The slope is zero.

So this is a horizontal line of the form y=1

Answer:

1. Reflection

2. Dilation

3. Rotation

Step-by-step explanation:

Hey!

You can tell number one is a reflection because it didn’t change side or turn upside down or anything, it just flipped over to the other side.

You can tell number two is a dilation because it changes size.

You can tell number three is rotation because it rotated.

Hope this helps! :D
