Form a right angle triangle joining both given points to the origin, we get:
Perpendicular = 2 ( distance is always positive)
Base = 4 ( same logic)
Applying Pythagorus theorem
Hypotenuse = root of ( perpendicular squared + base squared)
Hypotenuse = root of 20 = 2 * root 5
Using x instead of theta
Sin x = perpendicular/hypotenuse
Cos x = base/hypotenuse
Sin x = -1/ root 5
Cos x = -2/ root 5
High probability of this answer being wrong.
Double check recommended.
Answer:
C is correct if I'm doing the math right. best of luck!!
Step-by-step explanation:
....... ..... ... .......4(x+11y)
= 3m-10m - 20 + 1/5
= -7m - 19 4/5
3/485 = 7/ x
then 3x = 7*485 = 3395
then x = <span>1131.67 kg/m<span>2
Hope this helps! Have a great day!</span></span>
