Answer:D
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 8.5%/100 = 0.085 per year
putting time into years for simplicity
6 months ÷ 12 months/year = 0.5 years
then, solving our equation
I = 10000 × 0.085 × 0.5 = 425
I = $ 425.00
on a principal of $ 10,000.00
at a rate of 8.5% per year
for 0.5 years (6 months) is $ 425.00
Yes they are if that helps, if you still are unsure than just mesure them and you will see
The answer is 105 degrees! They are alternate exterior which means they are congruent! Also, they form vertical angles when you set them next to each other :)
