Sergio [31]

Answer:

A: adjacent angles: The angle ∠CFD & ∠DFE are directly  next to each other, making them <em>adjacent angles</em>.

B: Complementary angles: Note that m∠BFC measures at 90°. m∠BFE is a straight line, with 180°. This means that ∠BFE - ∠BFC = ∠DFE.

180 - 90 = 90 ∴ m∠DFE = 90°

Then to find the increased version, first find the area: 36 + 28 = 64

Now, the length.

Root 64 = 8

To find the factor it increased by:
