30.8cm

Explanation:

i am from connexus 8th grd pre algrabra

unit 5 lesson 3

1. 1:2

2. C. yes they are similar they have porportional side lengths and = ange measures

3. x = 4.5m

4. x = 30.8cm

5. x = 6 m

i hope this helps! = ) <3

Answer 2

x = 19cm

Explanation:

use pythagorean theorem:

a² - c² = b²

10² - 22² = b²

100 - 484 = b²

384 = b²

√384 = b

19cm = b or x
