Answer:
391.2cm²
Step-by-step explanation:
Triangle = 1/2bh*2=1/2(4)(6.9)(2)=27.6 for each end triangle.
14*8=112 for each rectangular side.
112+112+112+27.6+27.6=391.2cm²

Answer:
x = 13.
So the 3 angles are a = 44, b = 47 and c = 89 degrees.
Step-by-step explanation:
If these are the angles are the 3 angles of a triangle they sum to 180 degrees, so:
3x + 5 + 5x - 18 + 7x - 2 = 180
15x - 15 = 180
15x = 195
x = 195/15
x = 13.
He can divide by 2,3,4,6,8,12,16,24,32, and 48 but
