please help Pythagorean theorem
please answer all the question

Answer:
Step-by-step explanation:
Formula: [tex]a^{2} + b^{2} = c^{2}[/tex]
A.)
[tex]a^{2} + b^{2} = c^{2}[/tex]
[tex]4^{2} +3^{2} = c^{2}[/tex]
16 + 9 = [tex]c^{2}[/tex]
25 = [tex]c^{2}[/tex]
5 = c
__________________________________________________________
B.)
[tex]15^{2} + 8^{2} = c^{2}[/tex]
225 + 64 = [tex]c^{2}[/tex]
289 = [tex]c^{2}[/tex]
17
__________________________________________________________
C.)
[tex]11^{2} + 14^{2} = c^{2}[/tex]
121 + 196 = [tex]c^{2}[/tex]
317 = [tex]c^{2}[/tex]
17.8
__________________________________________________________
D.)
[tex]3^{2} + 3^{2} = c^{2}[/tex]
9 + 9 = [tex]c^{2}[/tex]
18 = [tex]c^{2}[/tex]
4.2
