Answer 1

Pertama mari kita selesaikan segitiga ABC terlebih dahulu

{ac}^{2} = {bc}^{2} + {ab}^{2}
{ac}^{2} = {8}^{2} + {6}^{2}
{ac}^{2} = 64 + 36
{ac}^{2} = 100
ac = akar 100
ac = 10

Untuk segitiga ACD

{ad}^{2} = {ac}^{2} + {cd}^{2}
{ad}^{2} = {10}^{2} + {24}^{2}
{ad}^{2} = 100 + 576
{ad}^{2} = 676
ad = akar 676
ad = 26
