Angle of elevation would be 66 degrees
Distribute the .15 on the right side to get:
20 + .5x + 3 + .075x
Then, combine like terms (add numbers together and add x terms together):
.575x + 23
...and that's your final answer!
Major arc, if it was semi circle, it would’ve been a half circle.
Minor arc if the circles angle was below a 135 degree angle.
Think of 40 as 100% (even though it is not)
X will be the value we are looking for
<span> If 40 is 100%, so we can write it down as 40=100%.
</span>
<span>We know, that x is 64% of the output value, so we can write it down as x=64%
</span>
-----------------------------------------------
1) 40=100%
<span>2) x=64%
</span>----------------------------------------------
<span>40/x=100%/64%
</span>
40/x=100/64
(40/x)*x=(100/64)*x
40=1.5625*x -divide both sides of the equation by (1.5625) to get x-
40/1.5625=x
25.6=x
x=25.6
So we get;
64% of 40=
25.6
