Giúp e bài T^2 và 2) vs ạ,đc cả hai bài càng tốt còn nếu ko giúp e một bài cx đc ạ,giải chi tiết giúp e e c.ơn nhìu lắm
Bài 2:
a: Ta có: ΔABC cân tại A
mà AH là đường cao
nên AH là tia phân giác của góc BAC
b: Xét ΔAMH vuông tại M và ΔANH vuông tại N có
AH chung
\(\widehat{MAH}=\widehat{NAH}\)
Do đó: ΔAMH=ΔANH
Suy ra: AM=AN
hay ΔAMN cân tại A
c: Xét ΔABC có AM/AB=AN/AC
nên MN//BC
d: \(AH^2-AN^2=HN^2\)
\(BH^2-BM^2=MH^2\)
mà HN=MH
nên \(AH^2-AN^2=BH^2-BM^2\)
hay \(AH^2+BM^2=BH^2+AN^2\)

Bài 2: Chọn C
Bài 4:
a: \(\widehat{C}=180^0-80^0-50^0=50^0\)
Xét ΔABC có \(\widehat{A}=\widehat{C}< \widehat{B}\)
nên BC=AB<AC
b: Xét ΔABC có AB<BC<AC
nên \(\widehat{C}< \widehat{A}< \widehat{B}\)
Cho ▲ ABC, đường trung tuyến AD. Gọi K là điểm ϵ AD sao cho \(\dfrac{AK}{KD}\)=\(\dfrac{1}{2}\). Gọi E là giao điểm của BK và AC. Tính tỉ số của \(\dfrac{AE}{EC}\)
giúp em giải bài này vs ạ em đag cần gấp em c.ơn trước ạ
Vẽ DM//BE=>DM//KE , theo định lí Ta-let thì trong tam giác ADM có :AK/KD=AE/EM=1/2
Xét tam giác BEC có : DM//BE nên EM/EC=BD/BC=1/2(định lí Ta-let)
Từ đó ta suy ra : AE/EC=AE/EM.EM/EC= 1/2.1/2=1/4

bạn biết được câu nào thì giúp mik, nếu có câu bạn hổng bít thì ko sao
cái này tớ ko biết câu nào hết cả
Mn giải giúp e bài này vs ạ
Tìm số tự nhiên n biết 3n+4 chia hết cho n-2
E đang cần gấp mong có câu trả lời sớm nhất ạ! E cảm ơn
3n + 4 = 3n - 6 + 10
= 3(n - 2) + 10
Để (3n + 4) ⋮ (n - 2) thì 10 ⋮ (n - 2)
⇒ n - 2 ∈ Ư(10) = {-10; -5; -2; -1; 1; 2; 5; 10}
⇒ n ∈ {-8; -3; 0; 1; 3; 4; 7; 12}
Mà n là số tự nhiên
⇒ n ∈ {0; 1; 3; 4; 7; 12}
mn giải giúp e bài 3, bài 4 với ạ, 12h đêm nay là hạn cuối ạ
Ai giải giúp e bài toán này trong ngày hôm nay vs ạ😭
9/25+ 2/11+10/17×16/25×9/11+7/17=?
=(9/25 + 16/25) + ( 2/11 + 9/11)+ (10/17 + 7/17)
= 1 + 1 + 1
= 3
Toán này đâu khó!
\(\dfrac{9}{25}+\dfrac{2}{11}+\dfrac{10}{17}+\dfrac{16}{25}+\dfrac{9}{11}+\dfrac{7}{17}\)
\(=\left(\dfrac{9}{25}+\dfrac{16}{25}\right)+\left(\dfrac{2}{11}+\dfrac{9}{11}\right)+\left(\dfrac{10}{17}+\dfrac{7}{17}\right)\)
\(=1+1+1\)
\(=3\)
