Step-by-step explanation:
82 + 76 + 42 = 200
42 out of 200 hmmm
200 / 2 = 100
42 / 2 = 21
21 out of 100 = 42 out of 200
=
21%
2x + 2x + x = 180°
5x = 180°
x = 36° (C)
Answer:
315
Step-by-step explanation:
1. This is not a scale rectangle and it angers me.
2. All you have to do is draw proportions.
5x7=35
15x21=315
Youll notice that 5x3=15 and 7x3=21 so it’s just proportions!
