Amanda has 4 in of green wire and 8 inches of red wire to make a triangle. how much purple wire does she need to complete triangle?

The length of the purple wire that Amanda needs to buy to make a triangle is 4 in.

Explanation:

Given:

Amanda has 4 in of green wire

                     8 in of red wire

Length of purple wire, l = ?

We know,

In an isosceles triangle two sides are equal.

If Amanda wants to make a triangle and buy a wire that could perfectly fit to make a third side then the minimum length of the wire should be 4 in as one of the sides of a triangle is 4 in.

Therefore, the length of the purple wire that Amanda needs to buy to make a triangle is 4 in.

answer is:

1.75 pounds

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
