A triangle has two sides with equal length and a third side 16 meters long. If the perimeter is 42 meters, what is the length of each of the equal sides?
Let x=length of one of the equal sides.
Then 42=16+x+x
Solve for x.
a triangle has two sides with equal length and a third slide 16 meters long. if the perimeter is 42 meters what is the length of each of the equal side
To find the length of the equal sides, we need to first determine the lengths of the other two sides. Let's call the length of each equal side x.
Given that the third side is 16 meters long and the perimeter of the triangle is 42 meters, we can set up an equation:
x + x + 16 = 42
Combining the x terms gives us:
2x + 16 = 42
Next, let's isolate the x term:
2x = 42 - 16
Simplifying the right side of the equation:
2x = 26
Finally, we can solve for x by dividing both sides of the equation by 2:
x = 26 / 2
Simplifying further:
x = 13
Therefore, each of the equal sides of the triangle is 13 meters long.
