A) 60o because similar triangles have corresponding angles equal so then by Angle Sum Property of Triangles you will get 60o
The distance traveled by the balloon in every minute makes an arithmetic sequence with a first term equal to 40 ft and common difference equal to 20. The nth term of an arithmetic sequence is calculated by,
an = a1 + (n - 1) x d
Substituting,
an = 40 + (15 - 1) x 20 = 320
Thus, the answer is letter B. 320 feet.
The answer is 18m^2. if u find the area of each section and add it up together at the end then u get 18
It would be 10500. Round the 450 to 500
