Answer: $40.33
Step-by-step explanation:
9% of $37 = 3.33
37 + 3.33 = 40.33
1,207+958=2,165 people
Hope this helps!
Answer:
Step-by-step explanation:
<u>Use the law of cosines:</u>
- cos C = (a² + b² - c²)/(2ab)
<u>Apply to the given triangle and solve for x:</u>
- cos x = (52² + 48² - 70²)/(2*52*48)
- cos x = 108/4992
- cos x = 0.02163461538
- x = arccos 0.02163461538
- x = 88.76°
A and b are legs
a^2+b^2=c^2
lets say
a>b
so
a=13+3b
c=14+3b
a^2+b^2=c^2
(13+3b)^2+b^2=(14+3b)^2
9b^2+78b+169+b^2=9b^2+84b+196
10b^2+78b+169=9b^2+84b+196
minus 9b^2 both sides
b^2+78b+169=84b+196
minus 84b both sides
b^2-6b+169=196
minus 196 both sides
b^2-6b-27=0
factor
(b+3)(b-9)=0
set to zero
b+3=0
b=-3, false, dimentions cannot be negative
b-9=0
b=9
shorter leg is 9
a=13+3b
a=13+3(9)
a=13+27
a=40
c=14+3b
c=14+27
c=41
side legnths are
9in, 40in, 41in
