apabila a dan b dua sudut berpenyiku dengan a=1/2b maka nilai a dan b berturut-turut adalah

A dan B sudut Berpenyiku
→a + b = 90

b = x
a = 1/2x

a + b = 90
x + 1/2 x = 90
2/2 x + 1/2 x = 90
3/2 x = 90
x = 90 : 3/2
x = 90 x 2/3
x = 60

a = 1/2x = 1/2 (60) = 30
b = x = 60

a = x.
b = 2x.

a + b = 90.
x + 2x = 90.
3x = 90.
x = 90/3.
x = 30.

a = x = 30.
b = 2x = 2(30) = 60.
