Step-by-step explanation:
Correct option is
A
3
: (2+
3
)
Given, ratio of angles are 4:1:1
⇒4y+y+y=180
o
⇒y=30
o
∴∠A=120
o
,∠B=∠C=30
o
Thus, the ratio of longest side to perimeter =
a+b+c
a
Let b=c=x⇒a

−2bccosA
⇒a

(1−cosA)
⇒a
2
=4x
2
sin

A
⇒a=2xsin
2
A
⇒a=2xsin60
o
=
3x
Thus, required ratio is
a+b+c
a
=
x+x+
3x
3x
=
2+
