Question

if triangle abc=90.ab=7cm.bc=24 find ac

Answer 1

Answer:

As perimeter of Δ ABC is 90°

third side = perimeter - (side 1 + side 2)

x = 90 - (7 +24)

x = 90 - 31

x = 59 CM

∴ AC = 59 CM

Answer 2

by,pythagoras theorem

ac^2= ab^2 + bc^2

= 7^2 + 24^2

= 49 +. 576

ac^2 = ✓625

ac. =. 25
