Question

Three sides of a equilateral triangle are respectively ,(x+3)cm.(y+4)cm & (x+y)cm Then the triangle whose sides are (2xy+1) cm ,(6x+1)cm.and (8y+1) cm is a .. what kind of a triangle? a) equilateral triangle b) scaling triangle c)isosceles triangle
​

Answer 1

Answer:

a)equilateral

Step-by-step explanation:

x+3=y+4=x+y

x+3=y+4           x+3=x+y

x-y=1                     y=3

x-3=1

x=4

a=2xy+1=25

b=6x+1=25

c=8y+1=25

a=b=c

So, triangle is equilateral.
