Plese i need help on this one !!!!!!!
patriot [66]

Answer:

I got 32.

Step-by-step explanation:

I used the Pythagorean theorem to find the lengths of the width and length. The length between (-1, 4) and (3, 3) was approximately 4 in. The distance between (-1, 4) and (-3, -4) was approximately 8 in. I then used those numbers to find the perimeter ((2*4)+(2*8))

Math help please <br> What is the length of AC¯¯¯¯¯ ?
irina1246 [14]

Answer:

AC = 6

Step-by-step explanation:

given ∠A = ∠C then triangle is isosceles with BC = AB, hence

3x - 8 = x + 4 ( subtract x from both sides )

2x - 8 = 4 ( add 8 to both sides )

2x = 12 ( divide both sides by 2 )

x = 6

⇒ AC = x = 6
