Question

9cm 17cm 8cm panjang sisi AC dan BC adalah​

Answer 1

[tex] \boxed{ \sf{ \mathfrak{ \underline{ \star \: diketahui \: \star \: }}}}[/tex]

[tex] \iff{ \sf{ba = 9 \: cm}}[/tex]

[tex] \iff \: { \sf{ad = 17 \: cm}}[/tex]

[tex] \iff \: { \sf{dc = 8 \: cm}}[/tex]

[tex] \boxed{ \sf{ \mathfrak{\underline{ \star \:ditanya \: \star }}}}[/tex]

[tex] \iff \: { \sf{ac = ... \: cm}}[/tex]

[tex] \iff \: { \sf{bc = ... \: cm}}[/tex]

[tex] \boxed{ \sf{ \underline{ \mathfrak{ \star \: jawaban \: \star}}}}[/tex]

[tex] \boxed{.} \boxed{.} \boxed{.}[/tex]

[tex] \sf{ {ac}^{2} = {ad}^{2} - {dc}^{2} }[/tex]

[tex] \sf{ {ac}^{2} = {17}^{2} - {8}^{2} }[/tex]

[tex] \sf{ {ac}^{2} = 289 - 64 }[/tex]

[tex] \sf{ {ac}^{2} = 225 }[/tex]

[tex] \sf{ac = \sqrt{225} }[/tex]

[tex] \boxed{ \sf{ \underline{ac = 15 \: cm}}}[/tex]

[tex] \boxed{ \sf{.}} \boxed{ \sf{.}} \boxed{ \sf{.}}[/tex]

[tex] \sf{ {bc}^{2} = {ac}^{2} - {ba}^{2} }[/tex]

[tex] \sf{ {bc}^{2} = {15}^{2} - {9}^{2} }[/tex]

[tex] \sf{ {bc}^{2} = 225 - 81 }[/tex]

[tex] \sf{ {bc}^{2} = 144 }[/tex]

[tex] \sf{bc = \sqrt{144} }[/tex]

[tex] \boxed{ \sf{ \underline{bc = 12 \: cm}}}[/tex]

[tex] \boxed{ \sf{.}} \boxed{ \sf{.}} \boxed{ \sf{.}}[/tex]
