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 
.
