✔ 最佳答案
h² = a² + b²h² = 25² + 60²
h² = 625 + 3600
h² = 4225
h = 65 cm

(length of the hypotenuse)^2= (lengths of the legs of a right triangle seperately)^2
(length of the hypotenuse)^2=(25)^2+(60)^2
(length of the hypotenuse)^2=625+3600
(length of the hypotenuse)^2= 4225
length of the hypotenuse= sqrt4225
length of the hypotenuse=65 answer..... D is correct option

The lengths of the legs of a right triangle are 25 cm and 60 cm.
sqrt (25^2 + 60^2) = sqrt 4225 = 65
Answer choice:
D.
65 centimeters
sqrt (25^2 + 60^2) = sqrt 4225 = 65
Answer choice:
D.
65 centimeters

the length of the hypothenuse is H so that :
H^2 = 25^2 + 60^2
= 625 + 3600
= 4225 = 65^2
therefore H = 65 ... cm --------> answer D
hope it' ll help !!
