Answer 1

Answer:

$\sqrt{89}$

question2 . 6$\sqrt{5}$

Step-by-step explanation:

question1.

$h^{2} = p^{2} +b^2\\ question2.\\longest side is the hypotenuse\\so, 18^2 = 12^2 +x^2 where .x. is. the. unknown$

Answer 2

Answer:

$\sqrt{89}$

Step-by-step explanation:

${5}^{2} + {8}^{2} = {c}^{2}$

25+64= c^2

c=

$\sqrt{89}$

12^2+b^2=18^2

b^2=324-144

b^2=180

b=6√5

I am not sure for the second one. Hope it helps :)
