if these are the angles then
let ratio=x
means 1x:3x:8x
in a triangle sum of all angles of atriangle is 180°
then
1x+3x+8x=180°
12 x=180
x=15
then 1x=15°
3x=45°
8x=120°
hope it help
then add to the brainlist answer please....

The sum of the three interior angles in a triangles is
180
∘
.
Given the three angles are in tte ratio of
1
:
3
:
8
,
let the three angles be
1
x
,
3
x
and
8
x
, respectively.
⇒
1
x
+
3
x
+
8
x
=
180
⇒
12
x
=
180
⇒
x
=
180
12
=
15
∘
⇒
1
x
=
1
×
15
=
15
∘
,
⇒
3
x
=
3
×
15
=
45
∘
,
⇒
8
x
=
8
×
15
=
120
∘
Hence, the measures of the three angles are
15
∘
,
45
∘
and
120
∘
180
∘
.

since, ratio of the angles of triangle = 1:3:8 let the angles be x, 3x, 8x sum of all angles of a triangle = 180 degrees so, x + 3x + 8x = 180 12x = 180 x = 180/12 x = 15 the angles of triangle = 15, 45, 120
