Answer:
3. A
4. D
5. C
Step-by-step explanation:
3.
WHOLE CIRCLE IS EQUAL TO 360°
to get the angle 3 add all the given then minus to 360
<1= 102° + <2=130° + <4 = 65° =297
297-360= 63°
4. the diameter is equal to 180° AC is diameter so the half circle is equal to 180° ABC is equal to 180 AB is equal to 110 BC is equal to 70 then CD is equal to 68° add all the given
110°+70°+68°=248°
5. BC is given it measure 70°
to get the missing or the ED we should add all the given and subtract to 360°
EA= 40
AB= 110
BC= 70
DC= 68
ED=?
40+110+70+68=288
288-360= 72
SO ED=72°
TO GET THE SUM OF ED AND BC WE SHOULD ADD THEM
ED+BC=
72+70=142
