Question

In a right - angled triangle, one of the acute angles is one fifth the other. Find the measure of the smallest angle. ​

Answer 1

Answer:

15 degree

Step-by-step explanation:

let one angle be x

then second angle =x/5

now,

    x+x/5+90=180

  x+x/5= 180-90

  5x+x/5=90

  6x/5=90

  x=90*5/6

  x=75

the measure of smallest angle= x/5 =75/5= 15 degree
