Answer:
Let the measures of the given angles of the triangles be (4x)o, (3x)o and (2x)o respectively.
Then,
= 4x + 3x + 2x = 180o … [∵sum of the angles of a triangle is 180o]
= 9x = 180o
= x = 180/9
= x = 20
So, the angle measures (4 × 20)o, (3 × 20)o, (2 × 20)o,
i.e., 80o, 60o, 40o.
Hence, the angles of the triangles are 80o, 60o, 40o.
