Question

a) In ΔPQR, PR is extended to S, as shown in Fig. 3. If ∠Q = x + 50, ∠P = 2x, and

∠QRS = 4x + 30, find the measure of ∠QRP in degrees.​

Answer 1

Anawer:

70 degree

Step by step explanation :

4x+30=2x+x+50

=3x+50

4x-3x+30=50

4x-3x=50-30

x=20

<qrs=4x+30

here x=20

=4×20+30

=110 degree

<qrp=180-110 degree

=70 degree
