Matematika tolong bantu penyelesaiannya scr runtut, terima kasih. ​

tolong bantu penyelesaiannya scr runtut, terima kasih. ​

pembahasan :

CF = √(12² + 10²)

= 2√61

CX = ½CF = ½×2√61 = √61

AC = √(20² + 10²)

= 10√5

AF = (20² + 12²)

= 4√34

RUMUS GARIS BERAT:

AX² = ½(AF² + AC²) - ¼CF²

= ½((4√34)² + (10√5)²)-¼(2√61)²

= 461

AX = 461
