Hey mate ,
We have been given value of perpendicular and hypotenuse of a right angle triangle and asked us to find the missing side i.e the base
So , According to Pythagoras theorem
Hypotenuse ² = Perpendicular² + base²
(10in.)² = (6in.)² + base²
100 - 36 Inches = base²
64inches = base²
√64 inches = base
Base :- 8 inches
