Answer: The measure of angle A is
ta có: B^+5=1,5A^\(\Leftrightarrow\)B^=1,5A^-5;C^+5=2,5A^\(\Leftrightarrow\)C^=2,5A^-5
mà tổng số đo của một tam giác : A^+B^+C^=180
\(\Leftrightarrow\)A^+(1,5A^-5)+(2,5A^-5)=180
\(\Leftrightarrow\)5A^-10=180
\(\Leftrightarrow\)5A^=190\(\Rightarrow\)A^=380

Answer: The measure of angle A is
Để tui dịch bài này cho :
Trong tam giác ABC, số đo góc B nhỏ hơn 1.5 lần số đo góc A là và số đo góc C nhỏ hơn 2.5 lần số đo góc A là
. Tính số đo góc A
Cách làm:
Đặt số đo góc A là x có:
x + (1.5x - 5) + (2.5x - 5) = 180
5x - 10 = 180
5(x - 2) = 180
x - 2 = 36
x = 38
Vậy góc A = 38 độ

Given two adjacent angles AOB and BOC. The sum of measure of them is equal to 160o and the measure of angle AOB is equal to 7 times the measure of angle BOC
a)Find the measure of each angle
b)Inside angle AOC, draw ray OD such that angle COD=90o. Prove that OD is the bisector of angle BOA.
c)Draw the opposite ray OC' of ray OC. Find the measure of 2 angles AOC and BOC' then compare them

Bạn ấy nói là:
Cho hai góc kề AOB và BOC. Tổng số biện pháp của họ là bằng 160o và là thước đo của góc AOB bằng 7 lần so với thước đo của góc BOC
a) Tìm các số đo mỗi góc
b) Bên trong AOC góc, vẽ tia OD sao cho góc COD = 90o. Chứng minh rằng OD là phân giác của góc BOA.
c) Vẽ OC ray đối diện 'của tia OC. Tìm các biện pháp của 2 góc AOC và BOC 'sau đó so sánh chúng
