3. A. have B. buy C. help D. take

4. A. chances B. months C. holidays D. times

VI. Read the passage and then answer the questions.

The two children have been in London. They were surprised at the crowds everywhere. They decided to travel on the tube railway. They found that they had to be quick and get on the train or it would go off without them.

One day they went to Hyde Park and walked along on the grass to Kensington Gardens in bright autumn sunshine. This was different from the crowded streets, and Mary said that it was like being back home. The leaves of the great trees were turning red, brown and yellow, birds were flying about, there were lots of flowers and ducks swimming about on the Round Pond. Only the noise from the street in the distance reminded them of the town.

Questions:

1. Where have the children been?

They have been in London

a: Xét ΔABD vuông tại A và ΔEBD vuông tại E có

BD chung

\(\widehat{ABD}=\widehat{EBD}\)

Do đó: ΔABD=ΔEBD

b: Ta có: AH\(\perp\)BC

DE\(\perp\)BC

Do đó: AH//DE
Ta có: \(\widehat{BIH}+\widehat{HBI}=90^0\)(ΔHBI vuông tại H)

\(\widehat{ADI}+\widehat{ABD}=90^0\)(ΔABD vuông tại A)

mà \(\widehat{HBI}=\widehat{ABD}\)

nên \(\widehat{BIH}=\widehat{ADI}\)

=>\(\widehat{ADI}=\widehat{AID}\)

=>ΔAID cân tại A

c: Ta có: \(\widehat{CAE}+\widehat{BAE}=\widehat{BAC}=90^0\)

\(\widehat{HAE}+\widehat{BEA}=90^0\)

mà \(\widehat{BAE}=\widehat{BEA}\)(ΔBAE cân tại B)

nên \(\widehat{CAE}=\widehat{HAE}\)

=>AE là phân giác của góc HAC

\(4x^3-x^2-ax+b⋮x^2+1\)

=>\(4x^3+4x-x^2-1+\left(-a-4\right)x+b+1⋮x^2+1\)

=>-a-4=0 và b+1=0

=>a=-4 và b=-1

a: ΔABC vuông tại A

=>\(\widehat{ABC}+\widehat{ACB}=90^0\)

=>\(\widehat{ABC}=90^0-30^0=60^0\)

Xét ΔBAD có BA=BD và \(\widehat{ABD}=60^0\)

nên ΔBAD đều

b: Xét ΔBAE vuông tại A và ΔBDE vuông tại D có

BE chung

BA=BD

Do đó: ΔBAE=ΔBDE

=>\(\widehat{ABE}=\widehat{DBE}\)

=>BE là phân giác của góc ABC

c: Ta có: \(\widehat{DAC}+\widehat{DAB}=\widehat{BAC}\)

=>\(\widehat{DAC}+60^0=90^0\)

=>\(\widehat{DAC}=30^0\)

Xét ΔDAC có \(\widehat{DAC}=\widehat{DCA}\left(=30^0\right)\)

nên ΔDAC đều

=>DA=DC

=>DC=DB

=>D là trung điểm của BC

=>\(AD=\dfrac{1}{2}BC\)

d: Xét ΔBMC có

BN,CA là các đường cao

BN cắt CA tại E

Do đó: E là trực tâm của ΔBMC

=>ME\(\perp\)BC

mà ED\(\perp\)BC

nên M,E,D thẳng hàng

=>BA,CN,DE đồng quy

mọi ng giúp e nhanh với, e cảm ơn rất nhiềuuu

a: Xét ΔABM và ΔACM có

AB=AC

BM=CM

AM chung

Do đó: ΔAMB=ΔAMC

b: ΔAMB=ΔAMC

=>\(\widehat{MAB}=\widehat{MAC}\)

Xét ΔAEM vuông tại E và ΔAFM vuông tại F có

AM chung

\(\widehat{EAM}=\widehat{FAM}\)

Do đó: ΔAEM=ΔAFM

=>AE=AF và ME=MF

ta có: AE=AF

=>A nằm trên đường trung trực của EF(1)

Ta có: ME=MF

=>M nằm trên đường trung trực của EF(2)

Từ (1),(2) suy ra AM là đường trung trực của EF

a: AI là phân giác của góc BAC

=>\(\widehat{BAI}=\widehat{CAI}=\dfrac{\widehat{BAC}}{2}=60^0\)

Xét ΔABD có AB=AD và \(\widehat{BAD}=60^0\)

nên ΔABD đều

=>BD=AB

   (\(x\) - 1) - (y - 1) 

\(x\) - 1 - y + 1

= (\(x\) - y)  - (1 - 1)

\(x\) - y - 0

\(x\) - y

Vậy phép tính trên là đúng.

Phép tính trên đúng

a: ΔABC cân tại A

=>\(\widehat{BAC}=180^0-2\cdot\widehat{B}=80^0\)

b: Xét ΔANB vuông tại N và ΔAMC vuông tại M có

AB=AC

\(\widehat{BAN}\) chung

Do đó: ΔANB=ΔAMC
