The picture below shows a portion of a river dam: a right angle triangle is shown with acute angle on base equal to 40 degrees and length of base equal to 100 meters. which of the following can be used to calculate the height of the river dam? 100 divided by sin 40 degrees 100 sin 40° 100 divided by tan 40 degrees 100 tan 40°

Using the base and the acute angle on the base, to find the height of the dam, you would need to multiply the base by the tangent of the angle.

Height = 100 * tan(40)

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

yeah i know the problem you need. i am taking it right now. the answer is step 3
