1st) reflection over the point G
2nd) a dilation of 1/2 with fixed point G
3rd) a traslation 2 units left and 4 units up
Solve for x by simplifying both sides of the equation, then isolating the variable
x= -1/4
The triangles are isosceles. The following notation are for the angles. For example ABD is refer to the angle located in the B vertex, formed by the segments AB and BD.
![ABD = ADB\\40 + 2ADB = 180\\ADB = 70 = ABD\\](https://tex.z-dn.net/?f=ABD%20%3D%20ADB%5C%5C40%20%2B%202ADB%20%3D%20180%5C%5CADB%20%3D%2070%20%3D%20ABD%5C%5C)
![70 + DBC + 30 = 180\\DBC = 180 - 100 = 80](https://tex.z-dn.net/?f=70%20%2B%20%20DBC%20%2B%2030%20%3D%20180%5C%5CDBC%20%3D%20180%20-%20100%20%3D%2080)
Then
![BCD = BCD\\2BCD + 80 = 180\\BCD = 50](https://tex.z-dn.net/?f=BCD%20%3D%20BCD%5C%5C2BCD%20%2B%2080%20%3D%20180%5C%5CBCD%20%3D%2050)
(-5+i)/2i
multiply by i/i
(-5+i) *i = -5i +i^2 = -5i -1
2i*i = 2i^2 = 2(-1) = -2
(-1-5i)/-2
1/2 +5/2 *i
