Question

Area of triangle formed by the positive x-axis, the normal & the tangent to the circle x2 + y2 = 4 at point (1,√3 ) is -

(A) √3/2 sq. unit

(B) √3 sq. unit

(C) 2√3 sq. unit

(D) 6 sq. unit

Answer 1

Correct option (C) 2√3 sq. unit

Explanation:

From figure we have to find out Area of ∆ OPA

tangent at P(1,√3 ) given by x + √3 y = 4 cut x axis at A (4, 0)
