Answer:
x = 45
Step-by-step explanation:
x and (90 - x) are alternate exterior angles and are congruent , then
x = 90 - x ( add x to both sides )
2x = 90 ( divide both sides by 2 )
x = 45

Answer:
Step-by-step explanation:
Because they are scaled copies, the ratios of the sides are equal.
Figure A has a base of 6 units by inspection.
Figure B has a base 3 units by inspection.
So, the scale factor from Figure A to Figure B is 
and we're done!
