Question

In a circle with centre o, seg XY is a chord of length 14 cm, Seg OA chord XY, then find (XA)​

Answer 1

Step-by-step explanation:

1:

In the adjoining figure the radius of a circle with centre C is 6 cm, line AB is a tangent at A. Answer the following questions.

(1) What is the measure of ∠CAB ? Why ?

(2) What is the distance of point C from line AB? Why ?

(3) d(A,B) = 6 cm, find d(B,C).

(4) What is the measure of ∠ABC ? Why ?

Answer 2

Answer:

A circle of centre P is drawn,

Chord AB is drawn of length 13cm as shown in figure. Let Q is the point on AB in such a way that PQ ⊥ AB.

we know, the chord is bisected by a line passing through centre and perpendicular upon it. here,

chord AB is perpendicular upon PQ.

so, AQ=QB=

AB

⇒AQ=QB=

13

=6.5 cm

hence, length of QB=6.5 cm

mark me as brainiest..
