Answer:
8°,32°,140°.
Step-by-step explanation:
Sum of measure of angles of a triangle is 180°
Let the second smallest angle be x°
Smallest angle= x
Largest angle= 5 x- 20°
A T Q
x+ x + 5x-20= 180°
= 180+ 20
= 200
x= × 4
x= 32°'
Smallest angle is 32°
Hence, the smallest angle is x=
×32°= 8°
Largest angle is 5x- 20= 5×32- 20= 140°
