What will the answer of 9​

Answer 1

Answer:

E=30

Step-by-step explanation:

let consider AXY

it is isosceles triangle

X=Y,A=30,X=Y=Z

formula of triangle

addition of all sides of triangle

180=A+X+Y

180=30+2Z

180-30=2Z

150=2Z

Z=150/2

Z= 75

X=Y=75

let consider triangle EFG

G IS THE OPPOSITE OS Z

G= Z=75

GFY is the isosceles triangle

G=F=75

FORMULA Of triangle

180=E+F+G

180=E+75+75 (75+75=150)

180-150=E

E=30
