Answer 1

5x - 20+ 2x - 10 = 180

7x - 30 = 180

7x= 180+30

7x = 210

x = 210/7

x= 30

your answer dear

Answer 2

Hey Mate!!

Given ; AB || CD. So, according to transversal rule ;

Angle BPO + Angle PQD = 180°

{5x-20°} + {2x-10°} = 180°

7x - 30° = 180°

7x = 180° + 30°

x = 210° / 7

x = 30°

Hope this helps you!!
