One side of a triangle is half the longest side. the third side is
7
feet less than the longest side. the perimeter is
38
. find all three sides.

The length of the sides are 9 units, 18 units and 11 units

Step-by-step explanation:

Let

x ----> one side of the triangle

y ----> the longest side of the triangle

z ----> the third side of the triangle

we know that

The perimeter of triangle is equal to

we have

so

----> equation A

-----> equation B

----> equation C

substitute equation B and equation C in equation A

solve for y

Find the value of x

--->

Find the value of z

---->

therefore

The length of the sides are 9 units, 18 units and 11 units

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!
