Answer» Hi , ( 2x- 8 ) and ( 3x - 7 ) are interior angles of the same side of the TRANSVERSAL . we know that , sum of interior angles of same side of the transversal = 180° 2x - 8 + 3x - 7 = 180 5x - 15 = 180 5x = 180 + 15 5x = 195 x = 195 / 5 x = 39 Therefore , 2x - 8 =( 2 × 39 ) -8 = 78 - 8 = 70° 3x - 7 = ( 3 × 39 ) - 7 = 117 - 7 = 110° I HOPE this helps you , :)

Hi ,

( 2x- 8 ) and ( 3x - 7 ) are interior angles of the

same side of the TRANSVERSAL .

we know that ,

sum of interior angles of same side of the

transversal = 180°

2x - 8 + 3x - 7 = 180

5x - 15 = 180

5x = 180 + 15

5x = 195

x = 195 / 5

x = 39

Therefore ,

2x - 8 =( 2 × 39 ) -8

= 78 - 8

= 70°

3x - 7 = ( 3 × 39 ) - 7

= 117 - 7

= 110°

I HOPE this helps you ,
