Question

Can someone pls help me

Answer 1

>> Answer

__________

$\:$

a² = c² - b²

a² = 9² - (√65)²

a² = 81 - 65

a² = 16

a = √16

a = 4

Answer 2

Use Pythagorean theorem

$\\ \sf\longmapsto P^2=9^2-(√65)^2$

$\\ \sf\longmapsto P^2=81-65$

$\\ \sf\longmapsto P^2=16$

$\\ \sf\longmapsto P=4$
