(AB) ²=(1)²+(2)²

(Ab)²=(5)

ab=root5

hypothesus=root5 OK friend

1,2,root5, is the right angled triangle of angle 90 degree OK friend

Answer 2

Answer:

1:2 =30:60

Step-by-step explanation:

in right triangle we 180-90=90 and let these ratio. be X and then:

X+2x = 90

3x=90

X=90÷3

X=30

now:

1x=30degree

2x=30*2=60degree
