1 answer:
zhuklara [117]3 years ago
8 0

Answer:

15 units

Step-by-step explanation:

ΔABC is right with ∠C = 90° and AB the hypotenuse

using Pythagoras' identity on the triangle

AB² = AC² + BC² , hence

BC² = AB² - AC² = 17² - 8² = 289 - 64 = 225

⇒BC = \sqrt{225} = 15 units

a = 8

b  = 10

a^3 =8^3 = 512

b^3= 10^3 =1000

a^3 + b^3 = 1512

a^2 = 64

-ab = - 80

b^2 = 100

a + b=18

(a + b) (64 -  80+ 100)
