We have an isosceles triangle:
The length of the sides are:
side₁=side₂=x
side₃=(x+x)-3=2x-3
Perimeter of a triangle=is the sum of the all sides.
we have this equation:
x+x+(2x-3)=29
4x=29+3
4x=32
x=32/4
x=8
The length of the third triangle will be: 2x-3=2*8-3=16-3=13
Answer: The length of the longest side of the triangle would be 13 meters.

1.
180-146 = 34
2.
(5y +3) + (4y +8) + 34= 180
9y +45 = 180
9y = 135
y = 15
