1200 * 0.05 * 4 = 240$ the amount of interest after 4 years.
total 1200+240=1440$
The two numbers are 48 and 18.
66 = l + s
l = 2 + 3s
66 = 2 + 3s + s
66 = 2 + 4s
66 - 2 = 64
64 = 4s
64 / 4 = 16
66 = l + 16
66 - 16 = 50
50 - 2 = 48
16 + 2 = 18
66 = 48 + 18
4y=-21+5
4y=-16
y=4

Answer:
Step-by-step explanation:
pythagoras theorem
a^2+b^2=c^2
8^2+9^2=x^2
64+81=x^2
145=x^2
=x
2 and 3 are the base angles because they are across from the legs (the 2 equal sides).
