From the info
You would use the tan x=5/2
But u would take the inverse of tan or 1/tan
The tan^-1(5/2)
=21.80140
The angle of b would be 21.80
Hope it helps
Answer:
Step-by-step explanation:So we know x + y = 21 and 5x +10y = 165 We line them up in columns x + y = 21 5x +10y = 165 To eliminate the x variable, I'll multiply every element in the 1st equation by -5. -5x + -5y = -105 5x + 10y = 165 Now we combine (add) the equations, which eliminates x altogether. 5y = 60 ... y = 12 From there, x + 12 = 21 ... x = 21-12 ... x = 9 You should double check. Do 9 nickles and 12 dimes equal $1.65? A very important thing to remember using this method is to do the same thing to each element in the equation that you change! I hope that helps.
Hey there,
Solution:
1 year = 7.75%
6 years = 7.75% x 6
= 46.5%
100% = 3400 km^2
1% = 3400km^2 / 100
= 11,560,000 / 100
= 115,600
46.5% = 115,600 x 46.5
= 5,375,400
Area left = 11,560,000 - 5,375,000
= 6,185,000
Hope this helps :))
