Step-by-step explanation:
The equation of the circle is
Tangent at point (1,7) will have slope equal to its derivative value
Differentiate to get
Using point slope formula
this line cuts x axis at (50,0) P
The triangle OAP has vertices equal to (0,0) (1,7) and (50,0)
The triangle has base as OP = 50 units
Height = distance of A from x axis = 7
Area = sq units
