Atriangle has a perimeter of 165cm the first side is 65 cm less than twice the second side the third side is 10 cm less than the second side find the length of each side of the triangle what equation represents the perimeter of the triangle if the second side is length s

The sides of the triangle are:

Second side = 60 cm

First side = 55 cm

Third side = 50 cm

The perimeter equation can be given as:

Step-by-step explanation:

Given:

Perimeter of triangle = 165 cm

First side = 65 cm less than twice the second side

Third side = 10 cm less than the second side

To find length of each side and write the equation that represents the perimeter of triangle.

Solution:

Let length of second side be = cm

First side will be given as = cm

Third side will be given as =   cm

Perimeter of triangle = Sum of all sides

Thus, perimeter can be given as:

⇒

⇒

Simplifying by combining like terms.

⇒

We know the perimeter of triangle = 165 cm

So, the perimeter equation can be given as:

Solving for .

Adding 75 both sides.

Dividing both sides by 4.

Thus, the sides of the triangle are:

Second side = 60 cm

First side = = 55 cm

Third side = = 50 cm

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

and also 19 is a. a sphere not a cirlcle

hope i !

pls mark me brainiest
