Question

Can someone pls help me

Answer 1

>> Answer

__________

`\:`

b² = c² - a²

b² = 10² - (√19)²

b² = 100 - 19

b² = 81

b = √81

b = 9

Answer 2

Use Pythagorean theorem

`\\ \sf\longmapsto P^2=H^2-B^2`

`\\ \sf\longmapsto P^2=10^2-(√19)^2`

`\\ \sf\longmapsto P^2=100-19`

`\\ \sf\longmapsto P^2=81`

`\\ \sf\longmapsto P=9`
