Answer:
2 - 
Step-by-step explanation:
Using the addition formula for tangent
tan(A - B) = 
and the exact values
tan45° = 1 , tan60° = , then
tan15° = tan(60 - 45)°
tan(60 - 45)°
= 
= 
Rationalise the denominator by multiplying numerator/ denominator by the conjugate of the denominator.
The conjugate of 1 + is 1 -
= 
← expand numerator/denominator using FOIL
= 
= 
= 
+ 
= 2 -
9900 because you divide 99000 by 10
The answer is 48.
8/14=x/84
Cross mutiply, to get:
14x=672
Divide each side by 14
You get 48.
Hope this help!!! :)
Answer: He earned 0.831% interest in total.
