Step-by-step explanation:

Answer:
12.3 feet.
Step-by-step explanation:
As we are given that
is an right angled triangle.

And we have to find out the value of side OP to the nearest tenth of a foot by rounding off the value as seen in the attached figure as well.
By using Trigonometric functions in a right angled
, we know that:

Here,
is
, Perpendicular is side <em>OP</em> and Base is side <em>PN</em>.
So, 

Putting the values of <em>PN </em>and
.

Hence, the value of <em>OP </em>is
.
Answer:
i6 sqrt 5
Step-by-step explanation:
It cannot be 12i sqrt 5 as this is 26.8326....
it cannot be 18i sqrt 5 as this is 40.249...
It cannot be 8i sqrt 5 as this is 17.888....
It cnanot be 8i sq rt 10 as this is 25.298....
i6 sq rt 5 = sqrt -180
Answer:
It is =
Step-by-step explanation:
Because (6 x 1 = 6 ) + 1 x 1/100 = 6.1
