In the given triangle, Base = 30, Perpenidcular = x and Hypotenuse = 50
Pythagoras Theorem :
In the right angle triangle, the sum of square of perpendicular and the base is equal to the square of the hypotenuse.
Hypotenuse² = Base² + Perpendicular²
Susbtitute Hypotenuse =50 and Base = 30
Hypotenuse² = Base² + Perpendicular²
50² = 30² + x²
2500 = 900 + x²
2500 - 900 = x²
1600 = x²
x = 40
x = 40
Perpendicular x = 40
Missing side : x = 40
Answer : Missing side = 40
