Answer:
40
Step-by-step explanation:
Hope that helped have a nice day!
The little square in the angle means 90 degrees. so if you know one angle in that overall angle is 76 you just have to subtract 72 from 90 and get 18. but since its (x-6) is the answer you would take 18 and take away 6 to get 12
Answer:
3
Step-by-step explanation:
The force of friction is given in the scenario:
Force = 500 Newton
and the mass of the runner is 60 kg
To find the acceleration we need to use the relation between force, mass, and the acceleration of the object:

Where 'F' represents the force, 'm' represents the mass, and 'a' represents the acceleration.
Plugging the value of variables we get:

Solving for 'a' (acceleration) we get:
Newton/kilogram or meters/ second squared
So the acceleration of the runner is 8.33 meters/ second squared.
