Given:
Base length of triangle = 10 units
Height of triangle =
units
Length of hypotenuse of triangle = 12 units
To find:
Exact value of Cos A
Steps:
The cosine of any angle is equal to the length of the adjacent side by the length of the hypotenuse side.
So,
Cos A = 
Cos A = 
Cos A = 0.833
Therefore, the exact value of cos A is 0.833.

Answer:
10 units.
Step-by-step explanation:
By the Angle Bisector of a Triangle theorem:
? / 15 = 4 (10-4)
? / 15 = 4/6
? / 15 = 2/3
? = 15*2 / 3 = 10 (answer).
