Find the length of segment AC if AB = 7.8 cm and BC = 25 mm. How many

1.	Find the length of segment AC if AB = 7.8 cm and BC = 25 mm. How many solutions are there in each case? a Point B lies on segment AC. Point B lies on line AC.
Answer» $Given \: length \:of \: segment \:AB = 7.8 \:cm$ $and \: length \:of \: segment \: BC$ $= 25 \:mm$ $= \frac{25}{10} \:cm$ $= 2.5 \: cm$ $\red{Length \:of \: segment \: AC}$ $= AB + BC$ $\blue{ ( given \: Point \: B \: lies \: on \: segment \: AC )}$ $= 7.8 \:cm + 2.5 \:cm$ $= 10.3 \:cm$ THEREFORE., $\red{Length \:of \: segment \: AC}\green {= 10.3 \:cm }$ •••♪
