Tan x=opposite/adjacent
cot x=adjacent/opposite
so you need to inverse the fraction
tan x=.78 as a fraction is 78/100
-> inversed= 100/78=1.28=cot x
so it is the second option
Answer:
60 miles per hour southeast.
Step-by-step explanation:
We are told that the car is moving southeasternly, so that answers the question right off the bat. The car is moving 120 miles per 2 hours. We need to know how much it moves in one hour though, so we must divide hours and miles by 2. We ger 60 miles per hour.
The factored form of the equation is (x + 4)(x – 6) = 0.
19ft Estimate the length of one side of a square floor,if the area is 320 square feet.give the whole number that is closest to the amount. the square root of 320 is 17.88,rounded is 18.
