Find the side lengths of the triangle in this picture.​
ozzi

Answer:

Hypotenuse: 41 meters, Long leg: 40 meters, Short leg: 9 meters.

Step-by-step explanation:

According to the statement, we have the following information about the lengths of the right triangle:

Hypotenuse

3\cdot x + 14

Long leg

3\cdot x + 13

Short leg

x

By the Pythagoric Theorem, we have the following expression:

(3\cdot x + 14)^{2} = x^{2} + (3\cdot x + 13)^{2} (1)

9\cdot x^{2}+84\cdot x + 196 = x^{2} + 9\cdot x^{2} + 78\cdot x + 169

9\cdot x^{2} + 84\cdot x + 196 = 10\cdot x^{2} + 78\cdot x +169

x^{2} -6\cdot x -27 = 0

(x-9)\cdot (x+3) = 0

As length is a positive variable by nature, then the only possible solution is x = 9. Lastly, the side lengths of the right triangle are:

Hypotenuse: 41 meters, Long leg: 40 meters, Short leg: 9 meters.

What was the price per yard of fabric
GuDViN [60]
Fabric will run you from $1/yd to upwards of $20/yd, depending on what you want. If you're looking for a fairly basic fabric, you're probably going to pay around $5-8 a yard. Patterns have gotten really pricey, but here's a trick--always buy them on sale. Most fabric stores will have one or two pattern brands on sale for a couple bucks a piece at any given time, which beats the heck out of paying $20 for one. Thread is around $2.50 a spool (can be higher, depending on quantity and material), and I want to say a zipper will run somewhere in the vicinity of $3, depending on size and type.
Depending on your fabric, you're probably looking at around $25-30 total.
