tolong dijawab ya poinnya 25
Jawaban:
[tex] \frac{ab}{ \sin(30) } = \frac{ad}{ \sin(90 ) } \\ \frac{ab}{ \frac{1}{2} } = \frac{20 \sqrt[]{2} }{ \frac{ \sqrt[]{3} }{2} } \\ ab \sqrt[]{3} = 20 \sqrt[]{2} \\ ab = \frac{20 \sqrt[]{2} }{ \sqrt[]{3} } \\ ab = \frac{20 \sqrt[]{2} }{\sqrt[]{3} } \times \frac{ \sqrt[]{3} }{ \sqrt[]{3} } \\ ab = \frac{20 \sqrt[]{6} }{3} [/tex]
AC=✓((20✓6)/3)²+(20✓6)/3)²
=✓40/3
maaf kalo salah
jawab:
