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
