Question

Find the value of x° , y° and z° .
Please give the solving ​

Answer 1

Answer:

x° = 60°

y° = 55°

z° = 65°

Step-by-step explanation:

∠QPA = ∠PQR = 180° - 120° = 60°

∠RPB = ∠PRQ = 180° - 115° = 65°

180° = 60° + 65° + y

180° = 125° + y

y° = 180° -125° = 55°

Answer 2

Answer:

55°,60°,65°

Step-by-step explanation:

=> 120 + angle PQR = 180. linear pair

=> angle PQR = 60°

=> 115 + angle PRQ = 180 linear pair

=> angle PRQ = 65°

from triangle PQR

=> angle PQR + angle PRQ + y = 180

=> 60 + 65 + y = 180

=> y = 55°

x = angle PQR = 60° alt. interior angles

z = angle PRQ = 65° alt. interior angles
