Question

If (5x+30)° and 2x° are a pair of co-interior angles, find them. with process

Answer 1

Answer:

5x+30+2x= 180 [co interior angles]

=7x+30= 180

=7x= 180-30

=7x= 50

= x= 50/7

= x=7.14

therefor,

5x+30= 5*7.14+30=> 65.7 degrees

2x= 2*7.14=> 14.28 degrees

[HOPE THIS IS CORRECT AND HELPS!]

Answer 2

Answer:

(5x + 30)° + 2x° = 180°

=> 5x° + 30° + 2x° = 180°

=> 5x° + 2x° = 180° - 30°

=> 7x° = 150°

=> x = 150° /7

=> x = 21.42°

One angle = 5 × 21.42° + 30°

= 107.1° + 30°

= 137.1°

Another angle = 2 × 21.42°

= 42.84°

Ans. 137.1°, 42.84°

Hope it helps.
