Question

find the angles of a triangle whose intrrior and exterior anglee are in ratio of 2:7 also the other twp interior angke are in the ratio of 3:4​

Answer 1

Answer:

three angles of a triangle are 40* 60* and 80*.

Step-by-step explanation:

if ratio of interior and exterior angle =2:7

therefore 2x+7x=180 [exterior angle sum property]

so 9x=180*  x= 20*

so 2x=40* and 7x =140*

then by interior angle sum property -

3x+4x+40*=180

7x+40*=180*

x=20*

so 3x=60* aqnd 4x=80*
