U just solve for the s using like terms
Isn't this perpendicular for a cross shape
1. < DCE=< DEC in the picture
⇒<ABC=<DEC=< DCE=<BCA ⇒ the triangle ABC is isosceles
2. ⇒<GFE=<DCE=<DEC=<FEG ⇒ the triangle EFG is isosceles
⇒ the triangles ABC and EFG have 2 angles equals ⇒ ABC~ EFG
5. ⇒ < ABC=<GEF =<DEC= < DCE=< BCA ⇒ the triangle ABC is isosceles
6. < GFE = < BCA= < ECD = <DEC = <FEG ⇒ the triangle EFG is isosceles
⇒ the triangles ABC and EFG have 2 angles equals ⇒ ABC~ EFG
Nth term = a1r^(n-1)
4th term = 15* (1/3)^3 = 15/27 = 5/9
Answer:
8/12 ;; 66%
Step-by-step explanation:
If you have 4 questions, with each having 3 answers, then you have 12 options (the denominator). If one is correct for each answer, then the correct is 4/12. Then you have to find the remaining part to see what is wrong.
