Answer:
25 in and 9 cm
Step-by-step explanation:
Using Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x be the missing side
A
x² = 7² + 24² = 49 + 576 = 625 ( take square root of both sides )
x = [tex]\sqrt{625}[/tex] = 25
B
x² + 12² = 15²
x² + 144 = 225 ( subtract 144 from both sides )
x² = 81 ( take square root of both sides )
x = [tex]\sqrt{81}[/tex] = 9
Answer:
A) [tex]\sqrt{7^{2} +24^{2} }[/tex] = 25
B) [tex]15^{2} -12^{2} = B^{2}[/tex]
[tex]B^{2} =81\\[/tex]
B = 9
