Answer:
20°
Step-by-step explanation:
According to the question, pair of supplementary angles are x and 8x
since they are supplementary, their sum is equal to 180°
x+ 8x = 180°
9x= 180°
x= 180°/9
x= 20°
We will see that in step 6 the distributive property was used, so the correct option is B.
<h3>
Which property supports statement 6?</h3>
The distributive property says that:
A*(B + C) = A*B + A*C
In step 5 we have the equation:
3*(x + 7) = 84
And in step 6, we have:
3x + 21 = 84 (Where remember that 21 = 3*7)
Then we can see that in step 6 the distributive property was used, so the correct option is B.
