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
The answer would be 4/10 or in simplest form it would be 2/5
Answer:
227.5
Step-by-step explanation:
65 mhp
after 3.5 h
Just multiply
65 x 3.5 = 227.5
