Answer:
16 - 2r
Step-by-step explanation:
2 times by 4 - 2r = -2 times by r + 5
6 + 4r = -2r - 10
Change the number to its partner.
6 + 10 = -2r - 4r
16 = 2r
So, the answer is 16 - 2r
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
