Answer:

26

Step-by-step explanation:

We can use difference of squares:

(5 - i)(5 +  i) = 5^2 - i^2

i^2 = -1, so we have 25 - (-1) = 25 + 1 = 26

I will give brainliest!! THERE IS NO OTHER INFORMATION GIVEN!! In ⊙O, chord XY is 8 cm long and is 10 cm from O. What is the rad
Zielflug [23.3K]

Answer:

radius ≈ 10.77 cm

Step-by-step explanation:

The segment from the centre O to the chord is a perpendicular bisector.

Thus 2 right triangles are formed with legs 10 cm and 4 cm ( half of XY )

The radius r is the hypotenuse.

Using Pythagoras' identity, then

r² = 4² + 10² = 16 + 100 = 116 ( take the square root of both sides )

r = \sqrt{116} ≈ 10.77 cm ( to 2 dec. places )
