The law of cosines is used to find the measure of Z.

Vlad [161]

we know that

The formula of the law of cosines is

$z^{2}=a^{2} +b^{2}-2*a*b*cos (Z)$

in this problem we have

$16^{2}=18^{2} +19^{2}-2*18*19*cos (Z)\\256=324+361-684*cos (Z)\\256=685-684*cos (Z)\\-429=-684*cos (Z)\\\\cos (Z)=\frac{429}{684}\\\\ \\Z=arc\ cos(\frac{429}{684})\\\\\\Z= 51.157$

Round to the nearest whole degree

Z=51 degrees

therefore

<u>the answer is</u>

51 degrees

Consider the following series. 1 8 1 16 1 24 1 32 1 40 Determine whether the geometric series is convergent or divergent. Justif

PtichkaEL [24]

Answer:

Divergent

Step-by-step explanation:

Divergent, because as the series continues the range of the values increases.

The reverse would be the case in a convergent series.
