one angle of a triangle measures 110°. the other two angles are congruent. enter solve an equation to find the measure x of the congruent angles.

b. lifting dumbbell weight at 20-degree angle from the body after a 45-degree angle

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
