By my guess I would say
170+290=460 length
225+35=260 width
460•260=119,600 mi
Find the average :8.4+7.5+12.9+10.6 divided by four
B. same angle, congruent
c. both angles are 90 degrees so it equals 180 when added together
e. congruent angles
g. supplement means when 2 angles have a sum of 180 and since both are 90 it has a sum of 180
h.
Answer:
Step-by-step explanation:
Since there are missing data, let's discuss some facts about regular polygons and their angles.
1) The sum of its Interior angles is given by:

2) Since it is a regular pentagon, each interior angle is congruent:
Each interior angle:

3) If we trace an outside line, the external angle will be supplemental, i.e.

4) If we trace from each diagonal one line segment, in a regular pentagon that will form 3 triangles with one-third of 108º,i.e.,36º
As we can see, the in the picture below
