The circumference involves 360 degrees.
60 degrees is one sixth of the circle (60/360)
So, one sixth of 72 is 12.
To find the length of the ladder, you need to do Pythagorean theorem.
50^2 + 30^2 = x^2
2500 + 900 = x^2
x^2 =3400
x= square root of 3400
58.31 OR 10 root34
To find the angle:
tan theta = opposite/adjacent
50/30 = 5/3
theta = tan inverse of 5/3
= 59.04

Answer:
Answer:
-(18/49)=n or approximately n=-0.367
Step-by-step explanation:
our equation is: m(nx²-y)/z=5n in order to find n we need to substitute the values given in the question. when we substitute we get:
6*(n*(-2)²-(-3))/(-5)=5n
6(4n+3)/(-5)=5n (we distribute the 6 in the numerator)
24n+18/-5=5n (we multiply both sides by (-5))
24n+18=-25n (we subtract 24n from both sides)
18=-49n (divide both sides by (-49))
-(18/49)=n or approximately n=-0.367
