Question

in figure 5.38 L is parallel to M and parallel to N

angle QPS = 35 degree and Angle QRT = 55 degree
find angle PQR​

Answer 1

∠PQR =  90°  where L is parallel to M and parallel to N  ∠QPS = 35° & ∠QRT = 55°

Step-by-step explanation:

L is parallel to M and parallel to N

=>  L is parallel to M  & N is parallel to M

 L is parallel to M

=> ∠QPS = ∠PQm

=> ∠PQm = 35°

N is parallel to M

∠QRT = ∠RQm

=> ∠RQm = 55°

∠PQR = ∠PQm  + ∠RQm

=> ∠PQR =  35° + 55°

=> ∠PQR =  90°
