In the adjoining figure, PT is a tangent at point C of the circle. O is the circumcentre of ? ABC . If ACP = 118^0 , then the measure of x. is.
SolutionShow Solution. PT is tangent. Hence by theorem, PT 2 = AT x BT. PT 2 = 16 x (AT – AB) PT 2 = 16 x (16 – 12) PT 2 = 16 x 4 = 64. PT = 8 cm. Concept: Tangent to a Circle.
In the adjoining figure, PT is a tangent at point C of the circle. O is the circumference of TABC. If +ACP =118c, then the measure of +x is (a) 28c (b) 32c (c) 42c (d) 38c Ans : We join OC as shown in the below figure. Here OC is the radius and PT is the tangent to circle at point C. Thus OC = PT +OCP =90c Given, +ACP =118c +ACO = ++ACPO? CP = 118 90cc? =28c +ACO =28c, In the adjoining figure, PT is a tangent at point C of the circle. O is the circumcentre of TABC. If +ACP =118c, then the measure of +x is (a) 28c (b) 32c (c) 42c (d) 38c Ans : (a) 28c Join OC as shown in the below figure. OC is the radius and PT is the tangent to circle at point C. OC = PT +OCP =90c Given, +ACP OA=118c +ACO =++ACP OCP-22=118 90cc-+ACO =28c, 11/16/2019 · Can you explain this answer? is done on EduRev Study Group by Class 10 Students.

In the given figure , PA and PB are tangents at points A and B respectively to a circle with centre O. If C is a point on the circle and ?APB = 40°, then ?ACB is equal to (a) 80°, In the adjoining figure, PT is a tangent to the circle with centre C. Given CP = 20 cm and PT = 16 cm, find the radius of the circle. Solution: We know that, Radius is always perpendicular to tangent . i.e, CT ? PT . Therefore, CPT is a right angled triangle, where CP = hypotenuse.
