Answer:
15
Step-by-step explanation:
since both equations are set with a right angle, the equation must be equal to 90 degrees. So you set the equation as
13+x+4x+2=90
add the x variables together and the constants separately
15+5x=90
then subtract 15 from both sides.
15+5x=90
-15 -15
5x=75
then divide 5 from both sides.
75/5= 15
so x is 15 :).

The distance of the portion of Earth that can be seen is:
Answer:
SSS
Step-by-step explanation:
REM and DME share a side. This side is of course congruent.
In addition, sides RM and ED are marked as congruent, as are RE and MD.
All three corresponding sides of each triangle are congruent, which proves the triangles' congruency.
No information is given about the angles in these triangles, so none of the other theorem answer choices are valid.
