Answer:
29°
Step-by-step explanation:
151° + a=180°
We know the sum of angles in a straight line is 180°
a= 180°-151°
The sign changed as it changed sides
a= 29°
Answer:
x = 0 and x = -2 are solutions of the given rational equation.
Step-by-step explanation:
We must solve the following rational equation:

Now we present the procedure:
1)
Given
2)
Compatibility with multiplication/Existence of the multiplicative inverse/Definition of division/Modulative property.
3)
Distributive property/
4)
Compatibility with addition/Existence of the additive inverse/Modulative property/Reflexive property
5)
Distributive property/
6)
Result
Now we check the rational equation with each root:
x = 0




x = 0 is a solution of the rational equation.
x = -2



x = -2 is a solution of the rational equation.
