Need help with this trigonometry word problem The angle of elevation of the top of the building at a distance of 50 m from its foot on a horizontal plane is found to be 60°. Find the height of the building.
Please show your work

Step-by-step explanation:

to find the height we need to use tan function because we are given adjacent and angle and we need to figure out opposite (height)

let opposite be AC

let adjacent be BC

according to the question:

now we need a little bit algebra to figure out AC (height)

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
