Question

Point A lies in the exterior of a circle with centre P and radius 10 cm. A tangent from A touches the circle at B. IF PA =26 cm find AB. ​

Answer 1

Step-by-step explanation:

sorry for the wrong point written in the middle of the statement

as the triangle is right angle

so,. used Pythagoras theorem

a^2+b^=c^2

Answer 2

Answer:

24 cm

Step-by-step explanation:

By Pythagoras theorem,

(PB)²+(AB)²=(PA)²

(10)²+(AB)²=(26)²

100 + (AB)²=676

(AB)²=679-100

(AB)²=576

(AB)²=√576

(AB)²=24cm
