DUDE WHAT GRADE R U IN!?!?!? IT'S SIMPLE ADDITION , BRO!!!
Perimeter = 4 x sides
48 = 4 (x + 3)
48 = 4x + 12
36 = 4x
x = 9
Check:
x + 3 = 9 + 3 = 12
12 x 4 = 48
1. given
2. perpendicular lines makes a right angle
5. definition of complementary angles
sorry bout the others. idk how to word it so hopefully what I gave you helps
