Answer:
x=80
Step-by-step explanation:
The angle of a line is 180*.
The equation would be (x+20)+x=180
Subtract 20 from both sides: 2x=160
Divide by 2: x=80
That's your answer!
I hope this helps!
Answer:
Step-by-step explanation:
All the sides are complete, hence we can use the information given to find just 1 triangle
Triangles
From the given information, we have that:
m<B = pi/6 = 30 degres
c = 10
b = 5
This shows that we can use the cosine rule to find the third side b of the triangle. Since all the sides are complete, hence we can use the information given to find just 1 triangle
Answer:
The rate at which water leaking is
gal/min.
Step-by-step explanation:
Given:
A large container holds 8 gallons of water.
After 56 minutes the container only has 1 gallon of water left.
Now, to find at what rate is the water leaking.
So, water leaked from the container = 8 gallons - 1 gallon = 7 gallons.
Time taken for leakage = 56 minutes.
<em>Now, to get the rate:</em>
![\frac{Gallons\ of\ water\ leaked}{Time\ taken\ for\ leakage}](https://tex.z-dn.net/?f=%5Cfrac%7BGallons%5C%20of%5C%20water%5C%20leaked%7D%7BTime%5C%20taken%5C%20for%5C%20leakage%7D)
![=\frac{7 gallons}{56 minutes}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B7%20gallons%7D%7B56%20minutes%7D)
![=\frac{1 gallon}{8 minutes}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%20gallon%7D%7B8%20minutes%7D)
The rate =
gal/min.
Therefore, the rate at which water is leaking is
gal/min.
I would say the answer is A and E
