b Name the sides of ABC.
c What side do 2 and 4 have in
common?
d Name the horizontal ray with end-point C.
e Estimate the sizes of BAD, 2, and
ABC.
f Are angles FCD and DCE different angles?
g Which angle in the figure is B?

Answer 1

Answer:

use Alex formula okkkkkkkkkkkkkkkkkkkkkkkkkkk

Answer 2

Considering the given figure, the required answers to questions are as stated below:

The given figure has lines and angles which has some relations. The application of the principles in geometry is required to solve this question. So that the following can be deduced from the figure:

1) a. The possible ways are: AR, AD, RA, RD, DR, DA

  b. Sides of <ABC are: AB and BC

  c. The side that both <2 and <4 have in common is FD

  d. The horizontal ray is CFEA

  e. <BAD is an acute angle. So that <BAD ≅ $60^{o}$

      <2 ≅ $60^{o}$

      < ABC is an obtuse angle. So that <ABC ≅ $120^{o}$

   f. <FCD and < DCE are the same in measure

    i.e <FCD = <DCE

  g. The angle in the figure that is <B is <D
