3 consecutive odd numbers....x, x + 2, x + 4

P = a + b + c
87 = x + x + 2 + x + 4
87 = 3x + 6
87 - 6 = 3x
81 = 3x
27 = x

x + 2 = 27 + 2 = 29
x + 4 = 27 + 4 = 31

ur 3 sides are 27,29,31...with 31 being the longest

X + (x+2) + (x+4) = 87

3x = 81 -> x = 27

So the longest will be 27 + 4 = 31

Help me pleaseeeee somebody ASAP

Answer:

x = 12

Step-by-step explanation:

In similarity triangles angles are congruent.

∠D = ∠A

x² - 8x = 48

x² - 8x  - 48 = 0

x² + 4x  - 12x - 48 = 0

x(x + 4) - 12(x + 4) = 0

(x +4)(x - 12) = 0

x - 12 = 0     {Ignore x + 4 = 0, as measurements won't have negative values}

x = 12
