4. Use a proportion to find the length of the missing side in the following similar figures. (1 point)
10 cm
22 cm
x= 28 cm
x= 30.8 cm
x= 6.4 cm
X = 19 cm

x = 19cm

Step-by-step explanation:

use pythagorean theorem:

a² - c² = b²

10² - 22² = b²

100 - 484 = b²

384 = b²

√384 = b

19cm = b or x

if x decreases by 4 then y increases by 10

step-by-step explanation:

555.99.
