Question

22. In the given figure, Find
i) PRS
ii) PTS
ni) ZSTR
iv) ZPRO
​

Answer 1

Step-by-step explanation:

In triangle PQR,

angle P+ angle Q + angle PRQ= 180° (Angle sum property of a triangle)

35° + 50° + angle PRQ= 180°

85° + angle PRQ = 180°

angle PRQ = 95°

angle PRQ + angle TRS = 180° (Linear pair)

95° + angle TRS = 180°

angle TRS = 85°

In triangle TRS,

angle STR + angle TRS + angle S = 180° (Angle sum property of a triangle)

angle STR + 85° + 45° = 180°

angle STR + 130° = 180°

angle STR = 50°

angle STR + angle STP = 180° (Linear pair)

50° + angle STP = 180°

angle STP = 130°
