Help please! math assignment

Answer 1

5, 10, 11

Explanation:

You could actually solve this problem 2 ways. You could use the pythagorean theorem, if you could confirm it was a right triangle.

But since they give you the perimeter, that will be the easy way.

Perimeter means all the sides added together will be 26

(x) + (x+5) + (2x+1) = 26

Now combine like terms

4x + 6 = 26

Subtract 6 from both sides

4x = 20

Divide both sides by 4

x = 5

Now we can plug the x back in the find the length of each side

(5) = 5

(5) + 5 = 10

2(5) + 1 = 11

Answer 2

The left side 5

The bottom 10

The slanted side 11

Explanation:

To find the perimeter of the triangle, add up the side lengths

x+ 2x+1 + x+5 = 26

Combine like terms

4x+6 = 26

Subtract 6

4x+6-6 =26-6

4x=20

Divide by 4

4x/4 = 20/4

x=4

The left side x = 5

The bottom x+5 = 5+5 = 10

The slanted side = 2x+1 = 2*1 +1 = 10+1 =11
