Step-by-step explanation:
- m <a+m <b+m <c=180 {sum of angles in a straight line are 180}
- 3x+5+5x-18+7x-2=180
- 15x-15=180
- 15x=180-15
- 15x=165
- x=165/15
- x=11
- so, m<a=3x+5=3×11+5=33+5=38
m<b=5x-18=5×11-18=55-18=37
m <c=7x-2=7×11-2=77-2=75
part B: no bcuz their sum isn't 90 whereas to be complement it must be 90
Answer:
15%

Answer:
B. They are similar, but not congruent.
Step-by-step explanation:
Draw a vertical rectangle 1 unit wide by 4 units tall.
Draw a segment showing the bottom 1 x 1 square and the top 1 x 1 square.
On the right side, 1 unit down from the top, draw a horizontal rectangle 2 units wide and 1 unit tall. Erase the part of the original rectangle where the two rectangles meet.
This is the top view.
It should look something like this:
