Which is the lowest interior angle ?

A triangle's interior angles must add up to 180 degrees, so x must equal 20. 

3x = 3 * 20 = 60

2x + 8 = 2 * 20 + 8 = 48

4x - 8 = 4 * 20 - 8 = 72.

48 > 60 > 72 so the lowest interior angle is 48 degrees. 

Hope this helps! Have a great day :)

~A triangles inner angles added equal 180

~Add all the angles
2x + 8 + 4x - 8 + 3x

~set equal to 180
2x + 8 + 4x - 8 + 3x = 180

~combine like terms
2x + 4x +3x + 8 - 8
9x = 180
x = 20

~now add 20 back into the angles
2(20) + 8 = 48
4(20) - 8 = 72
3(20) = 60

Therefore, 48 is the lowest interior angle so your answer is C.
If this helps leave a brainliest :-)

Chope this have a nice day btw the other person deserves brainlest
