On the ray with the origin at point A, points B and C are marked, it is known that AB = 10.3 cm BC = 2.4 cm how long a segment AC can have.
ray with origin at point A,
points B and C belong to ray c,
AB = 10.3 centimeters,
BC = 2.4 centimeters.
Find the length of the segment AC -?
Consider a ray with. Point B is located between points A and C. Therefore, the length of the segment AC is equal to the sum of the lengths of the segments AB and BC, that is:
AC = AB + BC (substitute the decimal fraction of 10.3 centimeters instead of AB, and the decimal fraction of 2.4 centimeters instead of BC);
AC = 10.3 + 2.4;
AC = 12.7 centimeters.
Answer: 12.7 centimeters.
