1. 5, 10,
A.45°-45°-90°
B.30°-60°-90°
C.neither

2. 15, 15, 21.2
A. 45°-45°-90°
B. 30°-60°-90°
C. neither

3. 11, 22, 19.1
A. 45°-45°-90°
B. 30°-60°-90°
C. neither

Answer 1

one number one the ending number is \[\sqrt[5]{3}\]

Answer 2

use the Pythagorean theorem\[a ^{2} + b ^{2} = c ^{2}\] for 30, 60, 90 triangles...\[a = 2b\] for 45, 45, 90 triangles \[a = b\] does this help?

Answer 3

yes thanks!
