<span>A midpoint divides a line or a segment into two equal parts. If D is the midpoint of the segment AC and C is the midpoint of segment DB, what is the length of the segment AB, if AC = 3 cm.</span>
If D is the midpoint of AC, then AD=DC
If C is the midpoint of DB, then DC=CB
If AC=3cm. then then DC-3/2=1.5
If DC=1.5 then CB is 1.5 also
AB=AC+CB
AB=3+1.5
AB=4.5
Given :
C, D, and E are col-linear, CE = 15.8 centimetres, and DE= 3.5 centimetres.
To Find :
Two possible lengths for CD.
Solution :
Their are two cases :
1)
When D is in between C and E .
. . .
C D E
Here, CD = CE - DE
CD = 15.8 - 3.5 cm
CD = 12.3 cm
2)
When E is in between D and C.
. . .
D E C
Here, CD = CE + DE
CD = 15.8 + 3.5 cm
CD = 19.3 cm
Hence, this is the required solution.
Answer: 25°
Step-by-step explanation:
From the question, Toothy the crocodile wants to eat a delicious chicken and his mouth is open to an angle of 30 degrees but he needs to open his mouth to the angle of 55 degrees for the chicken to fit.
The additional angle that Toothy's mouth needs to be open so he can eat the chicken will be:
= 55° - 30°
= 25°
Answer:
D = { -4,-1,3,5,6}
Step-by-step explanation:
The domain is the x values or the inputs
D = { 3,6,-1,5,-4}
We normally put them in order from smallest to largest
D = { -4,-1,3,5,6}
