Answer:
I think the angles of the triangle are 60°, 60°, 60°
I think the angles of the triangle are 60°, 60°, 60°Step-by-step explanation:
We know that the sum of the three angles of a triangle is 180°
so,
3x + (2x + 20) + (5x - 40) = 180
or, 3x + 2x + 20 + 5x - 40 = 180
or, 10x - 20 = 180
or, 10x = 180 + 20
or, 10x = 200
or, x = 200/10 = 20
so the number of first angle = 3 × x = 3 × 20 = 60°
the number of 2nd angle = 2x + 20 = 40 + 20 = 60°
the number of 3rd angle = 5x - 40 = 100 - 40 = 60°
see this answer I am not sure but hope it will help you
