Find the perimeter of ELPJ with the given information. If someone could write an explanation that would be awesome.

18 units

Step-by-step explanation:

The 4 sides are tangents to the circle

Perimeter = 2(2 + 4 + 1 + 2)

= 2(9)

= 18

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

7 is the median   7.875 is the mean
