Answer: i think you're talking about dilations and there are specific formulas depending on the situation.
for example: the dilation of (x,y) is (-1/2x, -1/2y).
you'd probably need to subtract 2 from whatever measurements of the shape you're working with. i'm not completely sure though
since the ∡C = ∡B, that means their corresponding sides stemming from the vertex A are equal, namely AC = AB.
2x - 24 = x - 2
x = 22.
It should be 14, because 8 - 2 = 6 and 12 - 4 = 8
Answer:
95 degrees
Step-by-step explanation:
since angles 1 and 4 are vertical angles, they are congruent
3x+10=4x-15
3x-4x=-15-10
-x=-25
x=25
x=25 degrees
angles 4 and 7 are supplementary due to them being alternate exterior angles
lets find the measure of angle 4:
4x-15
4*25-15
100-15
85 degrees
Now, lets find the angle measure of angle 7:
85+x=180
x=180-85
x=95
So, the angle measure of angle 7 is 95 degrees
