Step-by-step explanation:
For the 1st picture,
1 unit to the left and 3 units up.
Fir the 2nd picture,
We know the 90 degree counterclockwise rule is
[tex](x) \:(y) goes \: to \: ( - y)(x)[/tex]
So our new points will be
(-1,7)
(4,8)
(-2,2)
For the 3rd picture,
The new points will be
(-10,0)
(-6,2)
(-7,-1)
For the 4th picture,
A pentagon interior angles add up to 540.
We solve for x.
I cant really see the angles but just add up all the known angles and subtract them from 540 and that should get you your answer.
For 5th picture,
Exterior angles add up to 360 for every figure, a 13 sided polygon means it has 13 exterior angles. Since this is a regular polygon, the angles will all be equal.
[tex] \frac{360}{13} = 27 \frac{9}{13} [/tex]
Which equal
27.7
