Answer:

396 in²

Step-by-step explanation:

The general formula for the surface area of a prism is:

SA = 2ab + 2ac + 2bc, where 'a', 'b' and 'c' are equal to the lengths of the prism.  In this case, the lengths are 7 in, 6 in and 12 in.  Plugging these values into the equation:

SA = 2(7 * 6) + 2(7 * 12) + 2(6 x 12)

SA = 84 + 168 + 144 = 396 in²

Answer:

x = 9

TH = 12

Step-by-step explanation:

since TM is half of HM, the equation is:

2(21 - x) = 3x - 3

42 - 2x = 3x - 3

45 = 5x

x = 9

TH = 21 - x

TH = 21 - 9

TH = 12

Answer:

  72°

Step-by-step explanation:

The external angle E is half the difference of subtended arcs CG and DF.

  E = (CG -DF)/2

  2E = CG -DF . . . . . . multiply by 2

  DF = CG -2E = 160° -2(44°) . . . . . add DF-2E to both sides; substitute values

  arc DF = 72°
