Question

In Fig. 6.1, side QR of a ∆PQR has been produced to the point S. If ∠PRS = 115° and ∠P = 45°, then ∠Q is equal to,



​

Answer 1

Answer:

20 degree

Step-by-step explanation:

sum of all angles in a triangle = 180

m(P) + m(Q) + m(R) = 180

45 + m(P) + 115 = 180

160 + m(P) = 180

m(P) = 180 - 160

m(P) = 20

Answer 2

Answer:  If      ∠PRS = 115°

              And   ∠P = 45°

              Then  ∠Q= 70°
