Ответ:
3
Step-by-step explanation:
Both angles are congruent because they are opposite exterior angles.
6x+2=x+17
5x=15
x=3
Ответ:
x = 23 °
Step-by-step explanation:
6 x + 2 ° + x + 17 ° = 180 °
combine like terms
6x + x + 2 ° + 17 ° = 180 °
7 x + 19 ° = 180 °
7 x = 180 ° - 19 °
7 x = 161 °
x = 161 ° / 7
x = 23 °
Ответ:
Option B
Step-by-step explanation:
As shown at the graph:
The circle C ⇒ has a center at (0,0) and radius = 2
The circle C' ⇒ has a center at (0,0) and radius = 7
Circle C shown below was dilated with the origin as the center of dilation to create Circle C'
As the radius of Circle C' is greater than the radius of Circle C ⇒ so, this represents enlargement dilation.
So, the factor of dilation = 7/2
So, the rule will be![(x,y) \rightarrow (\frac{7}{2}x,\frac{7}{2} y)](/tpl/images/0550/5346/8ecb1.png)
The answer is option B
