Question

PQ parallel RS , find x​

Answer 1

Step-by-step explanation:

PQ ll RS ( given)

so,

LADS =120⁰ ( corresponding angle)

LBDE=180⁰-120⁰=60⁰ (linear pair)

similarly

LBED=180⁰-100⁰=80⁰

in∆BDE

LDBE+LBDE+LBED=180⁰(angle sum property)

x+60⁰+80⁰=180⁰

x+140⁰=180⁰

x=180⁰-140⁰

x=40⁰

plz relate this with figure,
