500/7 = 71.43 gallons per hour
950-500 = 450
450/71.43 = 6.3 more hours.
Answer:
The unknown sides are 60.81cm and 51.57cm while the unknown angle is 58degrees
Step-by-step explanation:
4a) Given the following
Opposite side = 38cm (side facing the given angle)
Required
Adjacent and hypotenuse side
According to SOH CAH TOA
![tan \theta = \frac{opp}{hyp}\\tan 32=\frac{38}{hyp}\\hyp=\frac{38}{tan 32}\\hyp=\frac{38}{0.6249}\\hyp= 60.81cm](https://tex.z-dn.net/?f=tan%20%5Ctheta%20%3D%20%5Cfrac%7Bopp%7D%7Bhyp%7D%5C%5Ctan%2032%3D%5Cfrac%7B38%7D%7Bhyp%7D%5C%5Chyp%3D%5Cfrac%7B38%7D%7Btan%2032%7D%5C%5Chyp%3D%5Cfrac%7B38%7D%7B0.6249%7D%5C%5Chyp%3D%20%2060.81cm)
Next is to get the adjacent
![Cos 32=\frac{adj}{60.81}\\adj=60.81cos32\\adj=60.81(0.8480)\\adj= 51.57cm](https://tex.z-dn.net/?f=Cos%2032%3D%5Cfrac%7Badj%7D%7B60.81%7D%5C%5Cadj%3D60.81cos32%5C%5Cadj%3D60.81%280.8480%29%5C%5Cadj%3D%2051.57cm)
Next is to get the missing
Since sum of angle in the triangle is 180degrees
32 + 90 + x = 180
122 + x = 180
x = 180 - 122
x = 58degrees
Answer: 60 degrees!
Step-by-step explanation:
75 - 15 = 60

<em>2x^2 + 10x</em> doesn't do anything, unless it's equal to something.
All you've got so far is a number. We can't even tell what it is
until we know what number 'x' is.
Is there another little part of the question that you didn't copy ?
