Answer:
50°
Step-by-step explanation:
in order ro find x you would need to solve for 101° ( x + 29) = 180° if you replace x with 50 then you equation would be true!
x = 50
101 + (x + 29) = 180
130 + x = 180
x = 180 - 130
A Exactly one solution
Putting y=0 at second equation, we have
The unique solution is
8.96 g/cm2
