Step-by-step explanation:
Have a nice day
Answer:
the answer is A
Step-by-step explanation:
Answer:
Angle 1 is 75 degrees (c) & Angle 2 is 105 degrees (e)
Sum of 6 & 7 is 180
Step-by-step explanation:
75 degrees is directly across from angle 1, meaning they are the same. These are <em>vertical angles</em>.
Angle 2 & 75 degrees are <em>supplementary angles</em>, meaning they add up to 180 degrees.
Knowing that, we can do 180 - 75 = 105
6 & 7 are also <em>supplementary</em>, meaning that they are equal to 180 (a straight line).
Hope this helped. :)
We have:
Method 1.
Use:
and the vertex form
(h, k) - the coordinates of a vertex
Answer: (-3, 8)
Method 2.
For the coordinates of a vertex (h, k) are equal
We have:
Substitute:
Answer: (-3, 8)
8 since the range is the highest number minus the lowest.
