The ratio of the measures of the three angles in a triangle is 14: 5: 11. find the measures of the angles.

Angle 1 . . . . . 14 parts
Angle 2 . . . . . 5 parts
Angle 3 . . . . . 11 parts

Total . . . . . . . . 30 parts

But the total of the angles in ANY triangle is always 180 degrees.

SO ... 180 degrees / 30 parts  =  6 degrees per part.

Angle 1 . . . . . 14 parts x (6° / part)  = 84°
Angle 2 . . . . . . 5 parts x (6° / part)  = 30°
Angle 3 . . . . . 11 parts x (6° / part)  = 66°

Check:  Total . . . . . . . . . . . . . . . . . . 180°  yay !

Kinetic energy = 1/2mv^2. since the mass is constant we can form a ratio of it's kinetic energy at 60 divided by that at 30 to see ke(60)/ke(30) = +(60^2)/30^2). this may be said to 300% increase.
