Answer:
96 degrees
Step-by-step explanation:
STR + STQ=180 degree
Substitute
x+x-12=180
2x-12=180
2x=192
x=96
If her original salary is x, then her new salary is 103% of x.
To obtain x from 43989, you therefore divide 43989 by 1.03 to get:
42708 (to nearest dollar).
You can the check it by multiplying by 1.03.
I think 2, 8, 5 <span>those are the factors that can be divided out to simplify the multiplication problem.</span>
(5*180)/7=900/7=128.5714285714286
The angle is approximately 129 degrees.
