Question

In a right - angled triangle, if one acute angle is half the other, then the smallest angle is

Answer 1

Answer:

30 degrees

Step-by-step explanation:

let one angle = x

second angle=x/2

third angle =90

sum of the angles in a triangle is 180degree

x+x/2+90=180

3x/2=90

x=90*2/3

x=30*2

x=60

the smallest angle=x/2=60/2=30 degrees

Answer 2

Answer:

30°

Step-by-step explanation:

90°+x+x/2=180°

x will be the bigger one
