Question

how to solve this figure​

Answer 1

Given,

AB || CD

So L BPQ + L DQP = 180°

$(5x - 20) + (2x - 10) = 180 \\ 5x - 20 + 2x - 10 = 180 \\ 7x - 30 = 180 \\ 7x = 210 \\ x = \frac{210}{7} \\ x = 30$

Answer 2

Answer:

Given,

AB || CD

Solution: BPQ + L DQP = 180°

➲ (5x - 20) + (2x - 10) = 180

➲ 5x - 20 + 2x - 10 = 180

➲ 7x - 30 = 180

➲ 7x= 180+30

➲ 7x = 210

➲ x= 210/7

➲ x = 30
