Answer:

-106

Step-by-step explanation:

the arithmetic equation is

an=a1+(n-1)d

a(25th)=14+(25-1)(-5)

14+(24)(-5)

14+(-120)

14-120

a25=-106

Angle DEF and angle FEG are supplementary. The measure of angle DEF = (9x +1) and the measure of angle FEG = (8x + 9). What is t

RUDIKE [14]

Supplementary angles are angles that are adjacent to each other and when summed to get a total of 180 degrees. In this case, DEF and FEG are supplementary. Thus the equation is 9x +1 + 8x + 9 = 180 = 17 x + 10; x then is equal to 10 so
<DEF = 9*10 +1 =91 degrees
<FEG = 8*10 + 9 = 89 degrees
