The legs of a right triangle are 12 centimetres and 16 centimeters. What is the length of the hypotenuse?

20 cm

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse h is equal to the sum of the squares on the other 2 sides, that is

h² = 12² + 16² = 144 + 256 = 400 ( take the square root of both sides )

h = = 20

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
