Answer 1

Answer:

Let the measures of the given angles of the triangles be (4x)o, (3x)o and (2x)o respectively. 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

Answer 2

Answer:

$sum \: of \: angles \: in \: a \: triangle \: is \: \\ supplementry. \\ 4x + 3x + 2x = 180 \: degree \\ = 9x = 180 \: degree \\ x = 180 \: degree \div 9 \\ x = 20 \: degree \\ \\ 4x = 4 \times (20)degree \\ 4x = 80 \: degree \\ \\ 3x = 3 \times (20)degree \\ 3x = 60 \: degree \\ \\ 2x = 2 \times (20 )\: degree \\ 2x = 40 \: degree$

the angels are 80°,60°,40°
