Rope skipping, general 12.3 881
Rope jumping, fast pace, 120-160 skips/min 12.3 881
Step-by-step explanation:
Answer:
∠abc=34°
∠dbc= 44°
Step-by-step explanation:
(5x+4)+(5x-6)=78
10x-2=78
10x=78+2
10x=80
x=8
put x in each equation
∠abc= 5x8-6
40-6
34°
78-34= ∠dbc
∠dbc= 44°
2 would be the lesser one
D^2 + 17d + 72 = 0
( d + 8 ) ( d + 9 ) = 0
d = - 8 , d = - 9
