Answer:
Option C
Players in basket ball team=12
No. of tape used per person=2
Since,3 ankles are tapped in 1 roll.
Therefore,roll used for 1 ankle=1/3
Roll used for two ankles or 1 person=2/3.
Therefore,
Total roles used=12×2/1 ×1/3
=8
Answer:
No cheating: you’re starring in a movie w/ the last person saved in your camera roll and the last song you listened to is the title.
"let's go everywhere" the movie with taemin and taeyong sounds like something i would watch ♡ https://t.co/tGdUt7CKPc
Answer:
no
Step-by-step explanation:
Triangles must add up to 180 degrees
Complementary is which add up to 90 °
8)
59+31=90° complementary angles.
supplementary is which add up to 180°
10) 156+24=18 supplementary angles
12)
shows right angle=3x+45=90
3x=45
x=15°
14) supplementary angles
2x+3x+25=180
5x+25=180
x=31°
16) again it makes supplementary angles
x+2x+21=180
3x+21=180
x+7=60
x=53°
ALTITUDE
the altitude is the height of the traignel
if we graph the points, we get some lopsided triangle
so we know the altitude is peerpendicular to the base
so find the line that is perpendicular to the line tha passes through A and C
so first fid the line that passes through (-4,-2) and (18,-8)
slope=(y2-y1)/(x2-x1)
slope=(-8-(-2))/(18-(-4))=(-8+2)/(18+4)=-6/22
perpendicular lines have slopes the multipy to -1
-6/22 times what=-1
times both sides by -22/6
wat=22/6
that is the slope of the line that is the altitude
we have to use point slope form
the equation of a line that passes through (x1,y1) and has sloe of m is
y-y1=m(x-x1)
so passes through B (4,4) and has slope of 22/6
y-4=22/6(x-4)
y-4=22/6x-44/3
y=(22/6)x-32/3
that is the altitude
MEDIAN
the media is the line joining the midpoint of one side to the vertex of the other
so we need to find the line that passes through the midpoint of AB and through the point C
midpoint of (x1,y1) and (x2,y2) is
((x1+x2)/2,(y1+y2)/2)
so
midopint of (-4,-2) and (4,4) is
((-4+4)/2,(-2+4)/2)=(0/2,2/2)=(0,1)
so we just find the line that passes through (0,1) and (18,-8)
slope iis (-8-1)/(18-0)=-9/18=-1/2
a point is (0,1) and sloe si -1/2
y-1=-1/2(x-0)
y-1=1/2x
y=(1/2)x+1
ALTITUDE
y=(-6/22)x
MEDIAN:
y=(1/2)x+1
