Answer with Step-by-step explanation:
We are given that point B lies on the segment AC.
Length of AC= a cm
We have to find the the distance between the midpoint of segment AB and BC.
When B lies on the segment AC.
Let mid point of segment AB and BC are E and F.
E is the midpoint of segment AB.
Therefore, 
Distance between E and F is given by
Hence, the distance between the midpoints of segment AB and BC is given by
The answer is 250 and 770
STEP 1:
Triangles= 180°
Other Angles= 7:13= 7x + 13x
Add all the angles to equal 180°
140° + 7x + 13x= 180°
combine like terms
140° + 20x= 180°
subtract 140 from both sides
20x= 40
divide both sides by 20
x= 2
STEP 2:
substitute x value to find other two angles
7x= 7(2)= 14° one angle
13x= 13(2)= 26° other angle
CHECK:
140° + 14° + 26°= 180°
140 + 40= 180
180= 180
ANSWER: The other two angles measure 14° and 26°.
Hope this helps! :)
Answer:
Step-by-step explanation:
All of the answer choices are in slope-intercept form.
The slope-intercept form is y=mx+b where m=slope and b=y-intercept.
Yes, because you have to add the like terms (14m and -6m which equals 8m) +9
