find the value of x. Round to the nearest degree

x = 51 degrees

Step-by-step explanation:

(to find x, use sine)

Sine =

⇒ Sine x =

⇒ = 0.78

⇒ Sine x = 0.78

then calculate what Sine-1 of 0.78 is:

⇒ Sine-1 of 0.78 = 51.26

x = 51.26

Round to the nearest degree:

51.26 ⇒ 51 degrees

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

answer: i think it is (1,-2)
