Using a scale of 2cm to 2 units on each axis, draw on a sheet of graph paper two perpendicular axes Ox and Oy for the intervals -10 a. Draw ;
i. ∆ABC with the vertices A(2,4) , B(4,8) and C(6,4)
ii. the image of ∆A'B'C' of ∆ABC under a rotation about the point P(-2,4) where A - A' , B - B' and C - C' through 180°about the point
b. from your graph, find ;
i. the angle of rotation (to the nearest degree)
ii. the coordinates of A' and B'.

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer

step-by-step explanation:

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
