Answer:
here you go
Step-by-step explanation:
35+a+b+c=270
35+a=90
a+b=180
35+90+c=180
Answer:Its B,C, and E man
Step-by-step explanation:
a+b+c=9 and a2+b2+c2=35 then by using identity
(a+b+c)2=a2+b2+c2+2ab+2bc+2ca,we get the answer 9x9=35+2(ab+bc+ca)
2(ab+bc+ca)=9x9-35
2(ab+bc+ca) =81-35then we get ab+bc+ca=46/2 so ab+bc+ca=23
