Let's say that the cost of the solar panel installation is 12,500 and the Reyes family pays 200 a month for electricity. in 40 years the Reyes family would have saved a lot of money on electricity.
f(480)=200(480) - 12,500
the Reyes family would save
83,500$ in 40 years.
Answer:
C. <ISN and <TSW
D. <TSN and <ISW

When two straight lines intersect each other, the two pairs of the opposite angles formed are called vertical angles.
In the figure given, we have two straight lines, NW and IT, which crosses each other. They form two pairs of opposite angles. They are:
<ISN and <TSW;
<TSN and <ISW.
These pairs of angles formed are vertical angles.
