We know: the sum of measures of triangle angles is 180°.
Therefore we have the equation
Substitute 
:
<h3>Answer: 180 - 7x</h3>
A is additive equality, where -x and x adds to 0
b is distributive, where x(y+z)=xy+xz
c is multiplicative equality, where x*1=x
d is subtracting both sides by 3.
Answer:
x = 3
Step-by-step explanation:
1. Plug 3 into g(x)
3 = -2x + 9
2. Subtract 9 on both sides
-6 = -2x
3. Divide by -2 on both sides to get x by itself
x = 3
