Any number written as a "percent" just represents the ratio of that number to 100. In the case of 42%, it's 42/100.

The perimeters of the triangles shown are equal.Find the side length of each triangle.
Anna11 [10]
I’m pretty sure you set the perimeters equal to each other, it would look like 3x+8+3x+7+3x = 3x+3x+4x+2 and then you add the similar ones so it would look like 9x+15 = 10x+2 then you subtract the two from both sides and subject the 9x from both sides and get 13 = x
AB would be 47
BC = 46
AC = 39
PQ = 39
QR = 39
PR = 54
then you could double check
47+46+39 = 39+39+54
132 = 132

(geometry) please look at attached image and help me with this question!
julsineya [31]

Answer:

  m∠AEC = 139°

Step-by-step explanation:

To make the equations easier to write, let's say all measures are in degrees, and define ...

  p = m∠AEB = 11x -12

  q = m∠CED = m∠CEB = 4x +1

Then ...

  p + 2q = 180

  (11x -12) + 2(4x +1) = 180

  19x -10 = 180 . . . . . . . . . . . . collect terms

  19x = 190 . . . . . . . . add 10

  x = 10 . . . . . . . . . . . divide by 19

  p = 11x -12 = 110 -12 = 98

  q = 40 +1 = 41

The angle of interest is ...

  m∠AEC = p +q = 98 +41

  m∠AEC = 139 . . . . degrees
