Let x be the base of the triangle, then the altitude will be (x−7).
Since the side of the triangle cannot be negative, so the base of the triangle is 12cm and,
the altitude of the triangle will be 12−7 = 5cm.
Step-by-step explanation:
base = x
altitude = x - 7
by Pythagoras theorem
Base² + height² = hypotenuse ²
divide the above equation by 2 we get
since x= -5 is neglected as it is negative.
