One way to determine the scale factor of a dilation is if you are using a graph then you can pick two corresponding points of the before and after and divide them and you can get the scale factor.
The second one is true because if you have 2 angle measures then you can automatically find the third because we know that all the angles of a triangle add up to 180 so lets say that one angle is 94 degrees and another is 38 degrees we would add those two up to get 132 and then we would subtract that from 180 to get the third angle which would be 48 degrees.
The third one, vertical angles have a common vertex, but they are never adjacent angles. Also, vertical angles are always congruent.
Answer:
Not congruent
Step-by-step explanation:
The sides that are equal in length are not in the same place if you align the triangles.
Answer:
30 first-class tickets were sold and 260 coach tickets were sold.
Step-by-step explanation:
Let a first-class ticket be represented by f and let a coach ticket be represented by c.
On a particular flight, a jumbo jet was carrying 290 passengers. So, the sum of the first-class tickets and coach tickets must sum to 290:

The total income was $95,280. Therefore:

We can now solve the system of equations. First, we can simplify the second equation by dividing everything by 8:

From the first equation, we can subtract f from both sides:

Substitute:

Distribute:

Simplify:

So:

From the previous equation:

Substitute:

30 first-class tickets were sold and 260 coach tickets were sold.
Hey!
So what you can do is:
1 x 1.5 = 1.5(2nd term)
1.5 x 1.5=2.25(3rd term) x 1.5=3.375(4th term) x 1.5 = 5.0625(5th term)
5.0625 x 1.5=7.59375(6th term)x1.5=<span> 11.390625
</span>11.390625 x1.5= 17.0859375(8th term)x1.5=<span> 25.62890625</span>(9th term)
The answer is D!
Hope this helps!
