Answer:
114
Step-by-step explanation:
to get the degrees of hexagon u should know first the greatest degree so you can subtract the others from it and how to get that
by this formula (no of sides-2)*180
(6-2)*180=720
so 138+128+120+160+90=606
and the remaining angle should be 720-606
which is 114
Answer:
s=√7-1
s=-(√7+1)
Step-by-step explanation:
s^2+2s-6=0
or,s^2+2.s.1+1^2=6+1^2
or,(s+1)^2=6+1
or,(s+1)^2=7
or,(s+1)^2=(±√7)^2
or,s+1=±√7
either,
s=√7-1
or,
s=-(√7+1)
The answer is the last option which is 9^6.... l hope it helped?
