Answer:

C. 28

Step-by-step explanation:

Because the two lines are parallel, according to the law of co-interior angles, they will add together to 180 degrees. (Because if you slide the 4x angle down past line g, they lie on the same line on either side of g).

Therefore we can write an equation to solve for x:

4x+(2x+12) = 180

Take out of brackets:

4x+2x+12 = 180

Combine terms and move 12 to other side:

6x + 12 - 12 = 180-12

6x = 168

Divide both sides by 6:

6x/6 = 168/6

x=28

Hope this helped!

The fish population of Lake Collins is decreasing at a rate of 3% per year. In 2004 there were about 1,300 fish. Write an expone
Sergeu [11.5K]
For this case we have a function of the form:
 y = A * (b) ^ x
 Where,
 A: initial amount
 b: decrease rate
 x: time in years
 Substituting values we have:
 y = 1300 * (0.97) ^ x

 For 2010 we have:
 y = 1300 * (0.97) ^ 6

y = 1083
 Answer:
 an exponential decay function to model this situation is:
 
y = 1300 * (0.97) ^ x
 The population in 2010 is:
 y = 1083

Plzzz help me with this ​
Illusion [34]
Ok, to prove the two triangles, we need reasoning:

1) the side AC is common (as you can see, both triangles share the side AC)

2) angle DCA is equal to angle BAC (this is due to alternate angles)

3) angle BCA is equal to angle DA (again, this is due to alternate angles)
