Answer:

B) 23,.8 feet

Step-by-step explanation:

It forms a right triangle.

We use the trigonometric ratio of cos to find the answer.

cos = adjacent /Hypotenuse

Here hypotenuse is the length of the ladder and adjacent side represent the ladder toughs the wall from the ground.

cos 18 = adjacent / 25

adjacent = 25*cos18

adjacent = 23.8 feet

Answer: B) 23,.8 feet

Hope this will helpful.

Thank you.

PLEASE HELP!!! Justin is running a race. He has completed 28 km, which happens to be 70% of the total race. How long is
tensa zangetsu [6.8K]
Answer is 40km
Explanation:
So in this question we can use a proportion
Since
28km is 70% we can write it equal to 70%
28=70

and since 100% is unknown we can write it equal to x
100=x

Then we put it in proportion form

28/x=70/100


Then cross multiply and divide

28(100)/70=x

Which would equal 40

If (k,6k) and (3k,10k) are two points on the graph of a line and K is not equal to 0, what is the slope of the line?
Nataliya [291]

Answer:

Step-by-step explanation:

slope = y2-y1/x2-x1

Given the coordinates (k,6k) and (3k,10k)

x1 = k

y1 = 6k

x2 = 3k

y2 = 10k

Substitute

slope = 10k-6k/3k-k

slopw = 4k/2k

slope = 4/2

slope  = 2

Hence the slope of the line is 2
