Answer/Step-by-step explanation:
3.a. length of AC.
Hypotenuse = AC
Opposite side to 60° = 7
Therefore, 
(to nearest tenth)
b. Length of BC
Hypotenuse = BC
Opposite side to 50° = 7
Therefore, 
(to nearest tenth)
c. Length of AB
Use the law of sines to find AB
m<C = 180 - (60 + 50) (sum of angles in a triangle) = 70°
m<A = 60°
BC = 9.1
AB = ?
Cross multiply
Divide both sides by sin(60)
(nearest tenth)
An arithmetic sequence would have a common difference between successive terms, not the case here.
A geometric sequence has a common ratio; let's check:
That's a common ratio of 3 so as far as we can tell a geometric sequence.
Answer: geometric
B cuz we *3*3*3 to reach to n 7
ok first you need to add e and 4 and get 95 out of haha
