Answer:
Hi there, I believe the answer to this equation is: 2.8
Step-by-step explanation:
Subtract 7 on both sides so
5n+7=21-7
you are left with 5n=14 you need to get n by itself so divide 5 on both sides.
5n/5 = 14/5
n=2.8
Hope this is correct :)
Have a great day
Answer:
3.5 m
Step-by-step explanation:
Use Pythagorean theorem to find the distance (d) the distance goes up the wall = adjacent to the angle 75° that is formed with the wall.
Length of ladder = the hypothenuse = 13.5 m
Thus, we would use:
Cos75 = adjacent/hypothenuse
Cos 75 = d/13.5
Multiply both sides by 13.5
13.5*cos(75) = d
13.5*0.2588 = d
3.4938 = d
d ≈ 3.5 m (nearest tenth)
