HOW to find hypotenuse if altitude and base is given?

HERE IS THE ANSWER THAT MAY HELP YOU:
LET BASE BE B
LET ALTITUDE BE A
LET HYPOTENUSE BE C²
BY APPLYING PYTHAGOREAN THEOREM,
A² + B² = C²


HERE BASE ( BC ) IS 12 cm AND ALTITUDE ( AB ) IS 5 cm.
WE HAVE TO FIND HYPOTENUSE ( AC )
BC² + AB² = AC²
12² + 5² = HYPOTENUSE²
144 + 25 = HYPOTENUSE²
169 = HYPOTENUSE²
HYPOTENUSE² = ROOT UNDER 169 = 13²
HYPOTENUSE = 13 cm
HOPE IT HELPS YOU!!!
