Hey there!
Solve using pythagoras theorem (given ∆ABC is a right triangle)
Pythagoras theorem ⇨ Hypotenuse² = Base² + Altitude²
In ∆ABC,
BC = 14 cm
AC = 48 cm
AB = c
Solve for c.
Hypotenuse² = Base² + Altitude²
c² = AC² + BC²
c² = 48² + 14²
c² = 2304 + 196
c² = 2500
c = √2500
c = 50 cm
Hope it helps ya!
