A lift in an office block has stopped at a restaurant on one of the floors. Call this floor zero . What floors does it stop at on the following sequence of journeys? Write each answer as either a positive or a negative number. A) up 8 floors
B) then down 17 floors
C) then down 12 floors
D) then up 20 floors
E) then down 14 floors

- 15

Step-by-step explanation:

Floor zero = 0

Up 8 floors = 0 + 8 = 8

then down 17 floors = 8 - 17 = -9

then down 12 floors = -9 - 12 = -21

then up 20 floors = -21 + 20 = -1

then down 14 floors = -1 - 14 = -15

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
