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 -
Answer:
Mid point of the given end points =
Step-by-step explanation:
Given the end points of the line segment are :
(0, ) & (
,0)
We will use the mid point formula when two points are: (x₁,y₁) & (x₂,y₂)
mid point =
now put the value of x₁ = 0
x₂ =
y₁ =
y₂ = 0
mid point =
=
That's the final answer.
