Answer:
B
Step-by-step explanation:
For supplementary angle the sum is 180°
5x + 20 + 50 = 180
5x + 70 = 180
5x = 180 - 70
5x = 110
x = 110/5
x = 22°
B is the answer because
745.88
2+2x=45
-2
0+2x = 43
2x = 43
0+x=41
X=41
8 out of 20 horses are brown
so
8/20
2/5
2/5 * 15 = 6
6 horses should be brown out of 15
Answer = decrease of 22 m/min
