Plz show work,... need help fast please

Answer 1

Explanation:

For 18:

`{10}^(2) + {y}^(2) = {26}^(2) \\ 100 + {y}^(2) = 676 \\ {y}^(2) = 676 - 100 \\ {y}^(2) = 576 \\ y = √(576) \\ y = 24 \: in`

For 19

`{10}^(2) + {( (15)/(2)) }^(2) = {c}^(2) \\ 100 + (225)/(4) = {c}^(2) \\ (625)/(4) = {c}^(2) \\ c = \sqrt{ (625)/(4) } \\ c = (25)/(2) \\ c = 12.5 \: m`
