Question

Tolong bantuin jawab nomer 1 yang A dan B pakai caranya ya..

Answer 1

A ) 180 = QPS + PSR
     180 = 2x + 100
      2x = 180 - 100
      2x = 80
       x = 40
sudut QPS = 2x = 2 (40) = 80 

b )  Sudut PQR = 3 x- 5 = 3 (40) - 5
                       = 120 - 5 = 115
     180 = y + 15 + 115
      180 - 130 = y
       y = 50
      
      sudut QRS = 50 + 15 = 65

Answer 2

A. 100 + 2x = 180 > 2x = 80 > x =40

jdi sudut QPS = 2x = 2 x 40 = 80

b. QRS = QPS
y + 15 = 80
y = 80-15 = 65

jd sudut QRS = 65+15 = 80
