First Problem:
4. A six meter ladder leans against a building. The ladder makes an angle of elevation of 60° with the ground. How far up the
wall does the ladder reach?
Which trig formula should I use?

Step-by-step explanation:

Here,ladder is making a right triangle with the wall and ladder is acting as hypotenuse.

Angle of elevation formed between ladder and wall is 60°. Length of ladder is 6 m and we need to find the height (h) of the wall where ladder reaches.

Thus, ladder reaches upto a height of 5.2 m of the wall.

6/20

step-by-step explanation:

i believe that the answer is

b. y-1=-2(x-4)

hope this !
