Is there any answer choices
Answer:
Let
a
=
8
and
b
=
8.5
Let the angle between
a
and
b
be
θ
Let the unknown side be
c
As
θ
→
0
,
88
c
→
0.5
As
θ
→
180
∘
,
88
c
→
16.5
So the lenght of side
c
will be in the interval:
0.5
<
c
<
16.6
Step-by-step explanation:
Angle 5 is 90 and because all the angles should add to 360 degrees, angle 4 is 20, and angles 3 and 6 are 70 and 70. 90+90+20+20+70+70= 360
42 ft 13in. that is the answer
