Answer:
Exact value of Cos(45° - 60°) is 0.96 using difference of two angles.
Step-by-step explanation:
Given:
Cos(45° - 60°)
We have to apply the formula of cosine for difference of the two angles.
Formula:

Plugging the values.
⇒ 
We know that the values :
and 
So,
⇒ 
⇒ 
⇒ 
⇒
...<em>rationalizing </em>
⇒ 
⇒
...<em>taking 2 as a common factor</em>
<em>⇒ </em>
To find the exact values we have to put the values of sq-rt .
As<em>, </em>
and 
Then
<em>⇒ </em>
<em />
<em>⇒ </em>
<em />
⇒ 
So the exact value of Cos(45° - 60°) is 0.96 using difference of two angles.
133 x 99 = 13167
