What does r mean. if r means multiply blank than 3*4 = 12
We have that
cos(alfa)=0.2546
arc cos (0.2546)=75.2501---------- > 75.25°
the answer is 75.25°
5=4x+2x-7
5+7=6x
12=6x
12/6=6x/6
2=x
Answer:
Step-by-step explanation:
note:when you do perpendicular lines you must change the slope to the oppisite and reciporcal
2y+4x=12
2y-1/4x=12
1/4x+2y=12
Answer:
The answer is 2.67
Step-by-step explanation:
AB = 3
BD = 2
AC = 4
BD and DE are parallel, AB/BD= AC/CE
3/2 = 4/CE
CE= 4*2/3
CE=8/3
Lastly, if you put it into decimal form, it is 2.67
