Answer: the number of seats in the 10th row is 36 seats and the number of total seats in cinema is 66 seats because there is 25 rows and the first row started out at 18 seats
Step-by-step explanation:
D) x=90, y=43
This is because sides AB and AC are equal so angles B and C are thus both 47.
Also, since both angles BAD and BAC are equal, and x is likely 90, that must be 180-(90+47)=43.
Answer:
b+6
Step-by-step explanation:
3b-2b+6=(3-2)b+6=b+6
Answer:
B'C'D'
Step-by-step explanation:
The figure was just translated, without any deformation, these are similar figures... so their corresponding angles are the same.
Since it was just moved down by 4 units, none of the angles were changed, and none of the side lengths were changed.
Since vertex C' corresponds to vertex C, the angle B'C'D' corresponds to original angle BCD.
