Answer:
±sqrt(T*L/m)=v
Step-by-step explanation:
T=mv^2/L
We want to solve the equation for v
Multiply each side by L
T*L=mv^2/L
*L
T*L=mv^2
Divide each side by m
TL/m=mv^2/m
T*L/m=v^2
Take the square root of each side
±sqrt(T*L/m)=sqrt(v^2)
±sqrt(T*L/m)=v
V=4x-1 I believe is the anwsers
Answer:
x = 65°
Step-by-step explanation:
The interior angle of the triangle and 140° are adjacent and supplementary, thus
interior angle = 180° - 140° = 40°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
105° is an exterior angle of the triangle, thus
x + 40° = 105° ( subtract 40° from both sides )
x = 65°
