Question

one of the exreriar angles of a triangle is 130 degree and the interiar opposite angles are in the ratio2:3 find the angles of the triangle​

Answer 1

Answer:

2x+3x=180 (angle sum propert)

then 5x =180

x=180/5

x=36

now 2x=2×36=72

3x= 3×36=108

Answer 2

Answer:

Let take ratios in 2x and 3x

Step-by-step explanation:

2x =180°

×= 180/2

= 90

3×=180

x=180/3

=60

The angles = 90+60

= 150°
