(a^3b^12c^2)*(a^5c^2)/(b^5c^4)^0= a. a^14b^15c^9

b. a^8b^12c^4

c. a^8b^17c^8

d. a^15b^12c^4

The construction of copying qpr is started below. the next step is to set the width of the compass to the length of ab. how does this step ensure that a new angle will be congruent to the original angle? by using compass take the measures of angle and draw the same arc according to it.
