Question

15) A number is chosen at random from the numbers -5, -4,-3, -2,-1, 0, 1, 2, 3, 4, 5.
Then the probability that square of this number is less than or equal to l is


16) In the given figure, AB, AC and AD are tangents. If AB = 5 cm, find AD.

OR
If the radii of two concentric circles are 4 cm and 5 cm, then find the length of each
chord of one circle which is tangent to the other circle.

17) Find the HCF of 96 and 404.
In the figure, if <ACB = <CDA, AC = 6 cm and AD = 3 cm, then find the length
of AB
​

Answer 1

Step-by-step explanation:

15) ans

E- event getting square of no .less or equal to 1

P(E) no of favourable outcome upon total outcome

3/11

this is ur ans

16)AB,AC andAD

Are tangents

if AB=5cm.

then AD And AC will be 5cm

because tangents to the circle are equal

hope this will help u
