Answer:
x = 13
y = 18.38
Step-by-step explanation:
tan 45 = x/13 (tangent = opposite / adjacent)
1 = x/13
multiply both sides by 13
x = 13
cos 45 = 13/y (cosine = adjacent / hypotenuse
0.7071 = 13/y
multiply both side by y
0.7071y = 13
divide both side by 0.7071
y = 18.38
Answer:
216 Months
Step-by-step explanation:
First find how much money he looses per month: 0+700-8000= -7300 on the first month. So 11600-7300=4300.
Then, he starts loosing $200 dollars per month because 900-700=200.
So 4300/20=215. So 215+1=216 months before Anthony runs out of money.
