The work done by a force  , that displays an object through a distance  d  is defined as  . this can also be expressed as  . alexa is pushing a construction barrel up a ramp 4 feet long into the back of a truck. she is using a force of 120 pounds in a horizontal direction and the ramp is 45  from the horizontal. how much work is alexa doing? a. 228 ft-lb c. 312 ft-lb b. 286 ft-lb d. 339 ft-lb

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
