Step-by-step explanation:
Correct option is D)
Let the acute angle be x.
Given, the acute angle is half of the other.
Then the other angle is 2x.
We know, by angle sum property, the sum of angles of a triangle is 180
o
.
⟹ 90
o
+2x+x=180
o
⟹ 3x=180
o
−90
o
⟹x=
3
90
o
⟹x=30
o
.
Hence, the angles are:
90
o
,x=30
o
and 2x=2×30
o
=60
o
