tentukan penyiku dan pelurus(atau keduanya jika ada) dari sudut2 berikut: A.25° B.45° C.60° D.70° E.105° F.132° G.37° H.10° I.90°

X = penyiku
Y = pelurus

A.25°
x = 90-25 = 65
y = 180-25 = 155

B.45°
x = 90-45 = 45
y = 180-45 = 135

C.60°
x = 90-60 = 30
y = 180-60 = 120

D.70°
x = 90-70 = 20
y = 180-70 = 110

E.105°
y = 180-105 = 75

F.132°
y = 180-135 = 45

G.37°
x = 90-37 = 53
y = 180-37 = 143

H.10°
x = 90-10 = 80
y = 180-10 = 170

I.90°
y = 180-90 = 90
