For number 5, if you know that one angle is 65 degrees, then you can find the angle of the supplementary angle by subtracting it from 180:
180 - 65 = 115 degrees < this is what your supplementary angle will be.
Starting from the top, the graph should read:
115 , 65
65 , 115
115 , 65
65 , 115
For number 6, all of the angles are right angles. We know that all right angles have a degree of 90, therefore every angle should be written as 90 degrees. Additionally, in order to find any supplementary angle, you take the known (90) and subtract it from 180. >> 180 - 90 = 90.

Answer:
the model has a ratio of 2:5 to the real tower
Step-by-step explanation:
Answer:
1. (7,-9)
2. (4,0) and (10,0)
3. (3,0) and (-3,0)
4. (0,-9)
5. (-1,-32)
Step-by-step explanation:
To find the vertex use the formula

First make the equation into a quadratic equation.

Now it is in the form

Now we can substitute the values

Now we have 7 as our x value for the vertex we can substitute for y,

So the vertex for 1 is (7,-9)
To find the intercepts for 2 & 3, they basically already give it to you. You just need to find a value for x for x-4 that will equal it to 0 and another for x for x-10 that will equal it to 0.

4 is slightly different but start the same,

Here, c (9) just shows the graph move down 9, so the y intercept = 9.
5 is the same process as 1,

Vertex,

Substitute,

So the vertex is (-1,-32)
