What is the common ratio for the geometric sequence?

Helen [10]

Note this pattern: Mult. 24 by (-1/4) produces -6.
Mult -6 by (-1/4) produces 6/4 = 3/2
Mult. 3/2 by (-1/4) produces 3/8

Looks as though you copied the problem down incorrectly. You wrote 32 for 3/2 and -38 for -3/8.

The common ratio is -1/4.

Find the last angle:
180-(30+90)
180-(120)
60

Evaluate using sine rule:
$\frac{c}{sinC}$ = $\frac{b}{sinB}$

c= $\frac{bsinC}{sinB}$

= $\frac{10sin90°}{sin30°}$

=20
