Question

Besar sudut QST adalah??

Answer 1

8x - 6 + 90 + 3x + 8 = 180
8x + 3x = 180 + 6 - 90 - 8
      11x = 88
          x = 88/11
          x = 8

∠QST = 3x + 8
          = 3(8) + 8
          = 24 + 8
          = 32⁰
Jawbannya B

Good Luck

Answer 2

(8x-6)+90+(3x+8) = 180 (pelurus)
(8x-6)+(3x+8) = 180-90
(8x-6)+(3x+8) = 90
11x + 2 = 90
11x = 90-2
X = 88 : 11
X = 8


Sudut QST = 3x + 8
= 3.8 + 8
= 32 (b)
