Answer:
67 degrees
Step-by-step explanation:
If angle a is 113 degrees, angle d will be 113 degrees subtracted from 180 degrees. Because angles in a straight line adds up to 180 degrees.
Answer:
816 cm²
Step-by-step explanation:
Surface area of the composite figure = (surface area of the larger rectangular prism + surface area of the smaller rectangular prism) - area of the side of the smaller rectangular prism that is joined to the bigger prism.
✔️Surface area of the larger rectangular prism:
Area = L*W*H = 20*5*6 = 600 cm²
✔️surface area of the smaller rectangular prism:
Area = L*W*H = 12*4*6 = 288 cm²
✔️area of the side of the smaller rectangular prism that is joined to the bigger prism.
Area = L*W = 12*6 = 72 cm²
Surface area of the composite = (600 + 288) - 72 = 888 - 72 = 816 cm².
Answer: At 01:05 p.m. it will overlap again.
Explanation:
Since there are 22 times in a day the minute and the hour hands overlap.
During the first half of the day , it overlaps 11 times and during the rest of the day it overlap 11 more times.
At noon, the minute and the hour hands overlap and after that it will happen at 01:05 p.m.
Since the minute hand completes a full circle in one hour, so it forms 6 degrees per minute .
So, at 01:05 p.m. it will overlap again.

They can be different because Daryl is doing it online so he will not have to swing arcs on the computer screen he will just use circles. Hope that this helps!
