please help and explain how to solve these! Thanks

Step-by-step explanation:
Use the Pythagorean Theorem to find the missing sides in the triangles.
[tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex]
Q2. [tex]c^{2}[/tex] = 8^2 + 40^2
[tex]c^{2}[/tex] = 1664
c = [tex]\sqrt{1664}[/tex]
c = 8[tex]\sqrt{26}[/tex]
Find the missing sides of the other triangles and figure out which ones are the same.
Q3. Do the same thing as Q2.
