Two sides of a triangle measure 10cm and 18cm. which could be the measure of the third side of the triangle?

s3>s2-s1  and s2+s1< s3

the third side must be greater than the difference of the other two sides

and must be less than the sum of the other two sides

s3 > 18-10

s3> 8

10+18 < s3

28 <s3

8<s3<28

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>
