Answer:
y+1 1/4=3 3/4 or y.1 1/4=3 3/4
Step-by-step explanation:
1/2x+20=1/3x+30
Subtract 20 on both sides
1/2x=1/3x+10
Subtract 1/3x on both sides
1/6x=10
Multiply by 6 on both sides
X=60
Call the angles of depression D.
then tan(D)=20/30, or I
arctan(tan(D)) = arctan(⅔)
D=33.690. A is the answer
your calculator probably uses tan^-1 rather than arctan
<h2>The height of cylinder is 11.8 meters</h2>
<em><u>Solution:
</u></em>
<em><u>
The volume of cylinder is given as:</u></em>
Where,
r is the radius and h is the height of cylinder
From given,
V = 95 cubic meters
r = 1.6 meters
h = ?
<em><u>
Substituting the values we get,</u></em>
Thus height of cylinder is 11.8 meters
