Question

Tolong bantuu makasihhhhhhhhhhhh

Answer 1

Verified answer

Seluruh sudut segitiga berjumlah 180°
sudut PSR = 140° dan sudut SPR = 30°
180° = 140° + 30° + sudut PRQ
180° = 170° + sudut PRQ
sudut PRQ = 180° - 170°
= 10°

Answer 2

Jumlah Sudut dalam segiempat = 360
<SRQ  + 140 + 60 + 140 = 360
<SRQ + 340 = 360
<SRQ = 360 - 340
<SRQ = 20
<PRQ = 1/2 (< SRQ) = 1/2 (20) = 10
