Question

an equilateral trangle has three sides it one side measure 5y second side measure 3y+16 find its all three sides​

Answer 1

Answer:

40 units

Step-by-step explanation:

As it is an equilateral triangle , it's all sides would be equal.

Given sides : 5y and 3y+16

Therefore,

5y = 3y+16

5y-3y = 16

2y = 16

y = 16/2

y = 8

Side of an triangle = 5y

= 5×8

= 40 units.

Answer 2

Answer:

Since all the sides of an equilateral triangle are equal

Then,

3y+16 =5y

16=5y-3y

16=2y

16/2=y

Therefore, y=8 (because 2×8=16)

So, the three sides are

5y=5×8

=40

3y+16=3×8+16

=24+16

=40

Therefore, the third side will also be 40 as it is equilateral triangle
