20 POINTS PLEASE HELP A 12-foot ladder that is leaning against a wall makes a 75.5 degree
angle ​with the level ground.
​
​Which of the following equations can be used to ​determine the height, y, above the ground, in feet, that the ladder ​touches the wall?
A
cos⁡ 75.5=Y12\cos \ 75.5=\frac{Y}{12}cos 75.5=
12
Y
​

B
cos⁡ 75.5=12Y\cos \ 75.5=\frac{12}{Y}cos 75.5=
Y
12
​

C
sin⁡ 75.5=Y12\sin \ 75.5=\frac{Y}{12}sin 75.5=
12
Y
​

D
sin⁡ 75.5=12Y\sin \ 75.5=\frac{12}{Y}sin 75.5=
Y

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

a mantle plume is an upwelling of abnormally hot rock within the earth's mantle. as the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts.

step-by-step explanation:

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
