Question

चित्र में PQ और ST रेखाएँ परस्पर T पर प्रतिच्छेद करती हैं। <QOT ज्ञात कीजिए।<br />R<br />In the figure PQand ST intersect at T Find <QOT:​

Answer 1

Answer:

we know that QOP is 180 °

QOS + SoR + por = 180°

3x + 4 x + 40 = 180

7x + 40 = 180

7x = 180-40

7x = 140°

x = 140/7 = 20 °

3x = 3×20 = 60°

4x = 4×20 = 80

SOT is also equal to 180°

QOS + QOT = 180 ° (linear pair )

60 + QOT = 180

QOT = 180 - 60

QOT= 120 °
