Vedclass · Answer

(A) In a right-angled triangle,the altitude to the hypotenuse creates two triangles similar to the original triangle and to each other.By the geometric mean theorem for the altitude: $BM^2 = AM \cdot CM$.Substituting the given values: $BM^2 = 4 \cdot 5 = 20$.Therefore,$BM = \sqrt{20} = 2\sqrt{5}$.In $\Delta ABM$,by the Pythagorean theorem: $AB^2 = AM^2 + BM^2$.$AB^2 = 4^2 + (2\sqrt{5})^2 = 16 + 20 = 36$.Therefore,$AB = \sqrt{36} = 6$.

In $\Delta ABC$,$m \angle B = 90^{\circ}$ and $\overline{BM}$ is an altitude to the hypotenuse $\overline{AC}$. If $AM = 4$ and $CM = 5$,find $AB$ and $BM$.
