Tan (x + π/2) = [sin (x + π/2) / cos (x + π/2)] = [sin x cos π/2 + sin π/2 cos x] / [cos x cos π/2 - sin x sin π/2] = cos x / - sin x = -cot x
They are alike because one kilometer is one thousand times more than one meter like one thousand is one thousand times more than one one. They are different because metric units are for measurement/volume/mass and place value units are for counting/numbers. HOPE THIS HELPS REEEEEEEEEE
Answer:
∠2 and ∠5 are corresponding angles
Step-by-step explanation:
5y+2(3y-1)=__y-(y+2)
5y+6y-2=__y-y-2
11y-2+2+y=__y
12y=___y
so 12
Answer:
Yes
Step-by-step explanation:
