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:
The third one.
Step-by-step explanation:
Hi there.
-12y < 36
Divide both sides by -12
-12/-12y < 36/-12
y > -3
The correct one is : C
Answer:
The answer is $450
Step-by-step explanation:
You need to do 150+150+150=450
or
150x3=450
