Question

One of the angles of a triangle is 180 degree and the interior opposite angle of it are in the ratio 4 : 2 find the angles of a triangle

Answer 1

Step-by-step explanation:

$sum \: of \: interior \: opposite \: angles \: equals \: to \: the \: exterior \: angle \:$

$4x + 2x = 180$

$6x = 180 \\ = x = \frac{180}{6} \\ = x = 30degree$

4x =4(30)=120°

2x=2(30)=60°

so the angles of triangles is 60 ,120,

hope it's helpful

Answer 2

Answer:

$4x + 2x = 180(exterior \: angle \\ \: property \: ) \\ 6x = 180 \\ x = 180 \div 6 \\ x = 30 \\ the \: angles \: are \: 120 \: and \: 60.$
