Answer:
AD= 15
AB=30
Step-by-step explanation:
We are given that the Point D bisect the line segment AB
Hence AD = DB
AD= 4x-1
BD=9x-21
Hence
4x-1=9x-21
adding 21 on both sides and subtracting 4x from both sides
4x-4x-1+21=9x-4x-21+21
-1+21=5x
5x=20
dividing both sides by x we get
x=4
Hence
AD = 4x-1
= 4(4)-1= 16-1=15
AD= 15
AB = 2 x AD
= 2 x 15
= 30
Your answer is 0.40 ......................
Answer:
19 Cds left.
Step-by-step explanation:
The question said he used 31 Cds, so 50 minus 31 is 19.
C it’s I think lol!!!!!^^*
Answer:
Step-by-step explanation:
Since they are adjacent the sum of the angles must equal 180 degrees.
17x+4+2x+5=180
19x+9=180
19x=171
x=9 making 17x+4=17(9)+4=157 degrees and 2x+5=2(9)+5=23 degrees
So the two angles are 23 and 157
