6. find the value of the unknown in each of the following figures​
b). Besarnya sudut segitiga sama kaki 180°
maka,
<a + <b + <c = 180°
68° + 64° + 2b° = 180°
132° + 2b° = 180°
2b = 180° - 132°
2b = 48°
b = 24°
d). <ABC = 180°
maka,
<a + <b + <c = 180°
3d° + 4d° + d° = 180°
8d° = 180°
d = 180° / 8°
d = 22,5°
f).<ABC = 180°
maka,
<a + <b + <c = 180°
f° + f° + f° = 180°
3f° = 180°
f = 180°/3°
f = 60°
