Cos = adjacent / hypotenuse
cos B = 4/5
B = cos^-1 (4/5)
B = 36.869897....
B = 36.87° (nearest hundredth)
Angle B = 36.87°.
The next bigger ten is 913,620 .
The next smaller ten is 913,600.
913,610 is exactly in the middle between them.
913,610 is already written to the nearest ten.
Answer:
B=9
Step-by-step explanation:
b+4=2b-5
b-2b+4=-5
b-2b=-5-4
-b=-5-4
-b=-9
b=9
I = Prt
I=1020
r=0.12 (12% converted to decimal by dividing by 100)
t=5
1020=P(0.12)(5)
1020=P(0.6)
P=1700
