Question

length of one side of a right triangle is 13.5 cm and the length of its hypotenuse is 22.5 cm. Find the length
of its third side.
20. A dice is tossed 40 times and the number 5 is obtained 14 times. Find the probability of getting the number 5​

Answer 1

Step-by-step explanation:

hypotenuse=22.5 cm

base= 13.5 cm

hypotenuse^2= base^2+ perpendicular^2

(22.5)^2= (13.5)^2+ perpendicular^2

(22.5)^2-(13.5)^2 = perpendicular^2

506.25- 182.25= perpendicular^2

324=perpendicular^2

perpendicular= 18 cm

THE THIRD SIDE IS 18 CM

Probability= no.of times 5 is obtained/ total no.of tosses

probability= 14/40

PROBABILITY= 7/20
