Answer:
A = 20sinθ(6 + 5 cosθ) cm²
Step-by-step explanation:
Drop perpendiculars DE and CF to AB.
Then, we have congruent triangles ADE and BCF, plus the rectangle CDEF.
The formula for the area of the trapezium is
A = ½(a + b)h
DE = 10sinθ
AE = 10cosθ
BF = 10cosθ
EF = CD = 12 cm
AB = AE + EF + BF = 10cosθ + 12 + 10 cosθ = 12 + 20cosθ
A = ½(a + b)h
= ½(12 +12 + 20 cosθ) × 10 sinθ
=(24 + 20 cosθ) × 5 sinθ
= 4(6 + 5cosθ) × 5sinθ
= 20sinθ(6 + 5 cosθ) cm²
Answer:
Group 1 = 4/10 (simplified 2/5)
Group 2 = 3/9 (simplified 1/3)
Step-by-step explanation:
There are 10 shapes in group one. There are 4 cylinders in those ten shapes. That means that theres a probability of 4/10.
Hope this helps! <3
Answer: A
Step-by-step explanation: is the proportional relationship!
All you have to do is $48.76 divided by 3 (cause thats how many students were there) and you get 16.253 but in money you can't do that so you would round it so the answer is $16.25. So they would all get $16.25 each.
