Answer:
60deg. and 80deg.
Step-by-step explanation:
We know that the sum of two interior angles of a triangle is equal to there opposite exterior angle .
The ratio given between angles id 3:4,so:
3x + 4x = 140
=7x=140
=x=140/7 =20
by this we can find the angles=
First angle = 3x
= 3 * 20 = 60 deg.
second angle = 4x
= 4* 20 = 80 deg.
