Help please! math assignment
MArishka [77]

Answer:

The left side   5

The bottom  10

The slanted side  11

Step-by-step 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
