Question

Tentukan nilai :
a. Nilai x ?
b. Besat sudut POR ?
c. Besar sudut QOR ?

Answer 1

Nilai x
= 2x +50 = 180
=2x = 180 -50
= 2x = 130
= x = 65
besar sudut por
= x + 20
= 65 +20
= 85
besar sudut QOR
= x + 30
= 65 + 30
= 95

Answer 2

X + 20° + x + 30° = 180°
x + x + 20° + 30° = 180°
2x + 50° = 180°
2x = 180° - 50°
2x = 130°
x = 130° / 2
x = 65°

POR = x + 20° = 65° + 20° = 85°
QOR = x + 30° = 65° + 30° = 95°
