Value of is .
Given:
To find: Find the value of , where , is positive acute angle.
Solution:
We know that,
is ratio of hypotenuse to side adjacent to angle .
Thus,
Apply Pythagoras theorem to find third side.
Step 1:
See the attached figure for better understanding.
As
So,
AB= 8k units
BC= 17k units
As, k be the common factor of ratio.
Step 2: Apply Pythagoras theorem.
BC²= AB²+CA²
or
or
or
or
Step 3: Apply ratio for
As
or
