Answer:
lol, hello again!
SA = 456 cm²
Step-by-step explanation:
small rectangle SA: 6*4 + 6*8 + 6*4 + 6*8 + 4*8 = 176
large rectangle SA: 2*14 + 2*8 + 2*14 + 2*8 + 8*14 + (8*14 - 8*4) = 280
Total SA = 176 + 280 = 456
The trick to solving this problem is to know and remember that the sum of all the interior angles of a triangle is always 180 degrees.
Thus, (6x+1) + (5x-17) + (9x-24) = 180.
20x = -40, so x = -2 (answer)
