Answer:70°
Step-by-step explanation:
Let the equal angles be x°,
Since we know that in a triangle sum of all angles is 180°
So, x°+x°+40°=180°
= 2x°+40°=180°
=2x°=140°
=x°=140°/2
=x°=70°
Hence eqal angles=x°=70°

Let the base angles be 'x'
Therefore,
x+x+40=180
2x=180-40
2x=140
X= 140/2
x = 70
Hence the base angles of the triangle are 70, 70
