a. Chủ ngữ: Xa quá khỏi Hòn một đỗi

    Vị ngữ: là bãi Tre

b. Biện pháp nhân hóa: tre - bình yên, thanh thản ; biển - giỡn sóng

c. tác dụng của biện pháp nhân hóa: làm cho những sự vật thiên nhiên ở bãi Tre trở nên sinh động, mang linh hồn con người.

d. Nội dung: Vẻ đẹp thiên nhiên ở bãi Tre

a) Trên nửa mp có bờ chứa tia OH , ta có 

   Góc HOI < Góc HOK ( 30⁰ < 80⁰ )

\(\Rightarrow\)Tia OI nằm giữa 2 tia OH và OK . Ta có :

    Góc HOI +Góc IOK = Góc HOk mà Góc HOI =30⁰ , Góc HOK = 80⁰

^{\(\Rightarrow\)}30⁰+Góc IOK = 80⁰

                  Góc IOk = 80⁰-30⁰

\(\Rightarrow\)        Góc IOK = 50⁰

b) Vì tia OI và OJ là 2 tia đối nhau \(\Rightarrow\)Góc IOJ = 180⁰ 

Trên cùng 1 nửa mp có bờ chứa tia OI , ta có :

       Góc IOk < Góc IOJ ( 50⁰ < 180⁰ )

\(\Rightarrow\)Tia OK nằm giữa 2 tia OI và OJ . Ta có :

        Góc IOK + Góc KOJ = 180⁰ mà Góc IOK =50⁰

\(\Rightarrow\)        50⁰+ Góc KOJ = 180⁰

                                 Góc KOI = 180⁰-50⁰

\(\Rightarrow\)                  Góc KOI = 130⁰

c) Vì tia ON là tia phân giác của Góc IOK , ta có :

       Góc ION = \(\frac{GócKON}{2}\)= \(\frac{50^0}{2}\)=25⁰

\(\Rightarrow\)Góc ION =25⁰

Bài làm:

\(2x.\left(\frac{1}{2.5}+\frac{1}{5.8}+\frac{1}{8.11}+\frac{1}{11.14}\right)=\frac{1}{21}\)

\(2x.\frac{1}{3}.\left(\frac{3}{2.5}+\frac{3}{5.8}+\frac{3}{8.11}+\frac{3}{11.14}\right)=\frac{1}{21}\)

\(2x.\frac{1}{3}.\left(\frac{1}{2}-\frac{1}{14}\right)=\frac{1}{21}\)

\(2x.\frac{1}{3}.\frac{3}{7}=\frac{1}{21}\)

\(2x.\frac{1}{7}=\frac{1}{21}\)

\(2x=\frac{1}{3}\)

\(x=\frac{1}{6}\)

vậy \(x=\frac{1}{6}\)
