The two parallel bases b1 and b2 are
b1 = 12
b2 = 9
the order of which base you pick doesn't matter
The height is h = 10 and it's perpendicular to each base.
The area is...
A = (1/2)*h*(b1+b2)
A = (1/2)*10*(12+9)
A = (1/2)*10*(21)
A = 5*21
A = 105
Final Answer: B) 105 square centimeters
Answer:
11
Step-by-step explanation:
17(3.25)=55.25
72.85-55.25=17.60

Answer:
You would put C. 46
Step-by-step explanation:
99+35
since the total of the 3 numbers would be 180°. so 99°+ 35° = 134°
then you do 180°-134°=46, so 46° is your answer!
