In ΔTUV, v = 940 cm, t = 730 cm and ∠U=168°. Find ∠T, to the nearest degree.

Step-by-step explanation:

use law of cosine. you can search on wikipedia.

find u. then use law of cosine again to find angle T. but i think you need use calculator

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
