Answer:
x = 12
Step-by-step explanation:
Vertical angles are congruent, so ...
4x = 48°
x = 12° . . . . . . divide by 4
Answer:
The ordered pair (1, 2) is a solution to the system of linear equations.
Pentagons have five sides, so 5x = 20. Only value for x that makes this true is 4, so 4 cm per side.
