Answer:
x=18
Step-by-step explanation:
So (3x+20)° and (5x-16)° are angles that are vertically opposite to each other; which means that they are equal to one another. Which means we can say:
(3x+20)=(5x-16)
20+16=5x-3x
36=2x
x=18
*and the two angles are 74°
If it is to match 3+1 which is 4 the value to satisfy X is -1
It wouldnt be reasonable bc a scale factor of 1 would make no difference therefore meaning there is no dilation.
Given:
Center of a circle is (3,9).
Solution point is (-2,21).
To find:
The standard form of the circle.
Solution:
Radius is the distance between center (3,9) and the solution point (-2,21).
On further simplification, we get
The radius of the circle is 13 units.
The standard form of a circle is
Where, (h,k) is the center and r is the radius.
Putting h=3, k=9 and r=13, we get
Therefore, the standard form of the circle is .
Finish the sequence 1,1,1,3,5,9,17,31,57, , ,

Your basically adding the first 3 numbers to get the next for example: 1,1,1=3
and then 1,1,3,=5 and then 1,3,5=9 then 3,5,9 =17 so on and so forth.
so to get the first answer of 105 I added the last 3 numbers in the sequence together (17,31,57) to get 105
the next 3 numbers in the sequence are:
105,193,355
