Cot A=1/tan A=12/5
cos A= 12/13
sin A=5/13
Draw a right angled triangle
the hypotenuse is the longest side which is 13 using Pythagoras theorem
the side opposite the angle A is 5
the side closest to the angle A which is called the adjacent is 12
sinA =opp/hyp
cos A= adj/hyp
cotA =1/tanA=cos A/sinA
Note: Pythagoras theorem is
hyp²=opp²+adj²
Answer:
Step-by-step explanation:
So first let us break how much trinkets one worker can make and find out the time frame. So the first two workers each can make a trinket in 90 seconds, 90/2 is 45 (seconds) for 1 worker. And the third worker takes 10 seconds longer, so 45+10 is 55 seconds for the third worker to make 1 trinket. There are 60 minutes in a hour, 60x60(seconds) is 3600 seconds in an hour. But here we will have to do 3600/100, because we forget about the individual time and focus on the combined time. So we add 10 more to 90, and now get 3600/100, which gives us out result of 36 trinkets made in an hour
