B - B - B - C - B - B - D
Nối A với B. (O) có \(\widehat{ACB}\) là góc nội tiếp chắn \(\stackrel\frown{AB}\), \(\widehat{ABM}\) là góc tạo bởi tia tiếp tuyến AM và dây AB chắn \(\stackrel\frown{AB}\) nên \(\widehat{ABM}=\widehat{ACB}=70^o\)
MA, MB là 2 tiếp tuyến của (O) tại A, B nên MA = MB => \(\Delta ABM\) cân tại M \(\Rightarrow\widehat{BAM}=\widehat{ABM}=70^o\)
\(\Delta AMB\) có \(\widehat{BAM}+\widehat{ABM}+\widehat{AMB}=180^o\Rightarrow\widehat{AMB}=180^o-\left(\widehat{BAM}+\widehat{ABM}\right)=180^o-70^o-70^o=40^o\)
