If the tangents at two points 1 2 and 3 6
WebIf AT is the tangent to the circle at the point A, then BAT is equal to (a) 65° (b) 60° (c) 50° (d) 40° Answer: (c) 50° Explanation: As per the given question: ∠ABC = 90° (angle in Semicircle is right angle) In ∆ACB ∠A + ∠B + ∠C = 180° ∠A = 180° – (90° + 50°) ∠A = 40° Or ∠OAB = 40° Therefore, ∠BAT = 90° – 40° = 50° 7. WebIf the lengths of the tangents drawn from the points (1,2) to the circle x 2+y 2+x+y−4=0 and 3x 2+3y 2−x+y+k=0 be in the ratio 4:3, then k= A 455 B 47 C − 455 D − 47 Medium Solution Verified by Toppr Correct option is C) Length of Tangent from point (x 1,y 1) = x 12+y 12+2gx 1+2fy 1+c So, 34= 3+12−1+2+k1+4+1+2−4 ⇒ 916= 16+k4 ⇒k= 4−55
