<h3>How to find the exact value of a trigonometric expression</h3>
<em>Trigonometric</em> functions are <em>trascendent</em> functions, these are, that cannot be described algebraically. Herein we must utilize <em>trigonometric</em> formulae to calculate the <em>exact</em> value of a <em>trigonometric</em> function:

You need help with geometry ?
A= a+b/2h =10+20/2 x13 =195
I believe 195 is correct if not, I’m so sorry
The nearest hole number would be 4 , if it is .5 and above then it gets rounded up to the next number and if it is .4 or less that you round it to the whole number
