Question

Laika notices a right angled triangle and observes that one acute angle is half the size of the other one. In
this case, the smallest angle would be:
I) 30°
II) 15°
III) 10°
IV) 25°

Answer 1

30 is the ans... Becoz... 30+30*2=90

Answer 2

30°because if one angle is 30° then other one would be its double
30°×2 =60°
According to the angle sum property
30° +60 °+90°=180°
