Answer:
LHS=cos^4(A/2)-sin^4(A/2)
={cos^2(A/2)}^2 -{sin^2(A/2)}^2
={cos^2(A/2) - sin^2(A/2)}{cos^2(A/2) +sin^2(A/2)}
=cosA×1
=cosA

Answer
im going to have to say the answer is B
Step-by-step explanation:
First look at it nothing can be above 0 so if the graph has 1 before 0 its wrong then u have completed one step of the equation.
Answer:
ft
Step-by-step explanation:
take angle b as reference angle
using sin rule
sin 45 = opposite / hypotenuse
= 17 / BC
BC =17 /
BC = 17 * 
BC = ft
