4(sin⁴ 60° + cos⁴ 60°) = 1 + 3(sin²60° - Cos² 60°)

Step-by-step explanation:

4(sin⁴ 60° + cos⁴ 60°) = 1 + 3(sin²60° - Cos² 60°)

sin 60°=

Cos 60°=

then do it by the calculator and they will be equal 2.5

I hope it will help

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
