Question

Tentukan nilai X° kemudian tentukan besar masing masing sudut pada gambar no.7 ya tlong bntu

Answer 1

Gambar (i)
3x + 2x = 90°
5x = 90
x = 18°

sudut ABD = 3x = 3(18) = 54°
sudut DBC = 2x = 2(18) = 36°

Gambar (ii)
7x + 2x = 90°
9x = 90
x = 10

sudut PQS = 7x = 7(10) = 70°
sudut SQR = 2x = 2(10) = 20°
