Answer:
12.
m∠ACB = 180° - 58° - 78° = 44°
m∠DCE = 180° - 85° - 60° = 35°
m∠BCD = 180° - 44° - 35° = 101°
13.
Base on the picture, we know that:
x° + 2x° + 3x° = 180°
6x° = 180°
x° = 180° ÷ 6 = 30°
=> m∠K = 2x° = 2 × 30° = 60°
=> m∠L = 3x° = 3 × 30° = 90°
=> m∠KML = x° = 30°
m∠LMN = 60° + 90° = 150°
it is b because it is multiplying by 2s.
The answer is C.
Explanation:
If you were to buy 5 games and they all cost $69.99 and you want to know to total cost, you would do $69.99 x 5 or count $69.99 five times.
The answer is 2,2 i already do the exam :D
6-4.7=1.3
7.3-6=1.3
8.6-7.3=1.3

d=1.3
-------------------------------------------------
a1=4.7
a2=a1+(n-1)d
6=4.7+1d→d=1.3
