Answer:
BD = 7 units || BC = 7√2 units
Step-by-step explanation:
(a)
if CA is 14, then CD = DA = 7
[tex]\frac{opposite}{adjacent}= tan(x)[/tex]
[tex]\frac{BD}{7}= tan(45)[/tex]
BD = 7 * tan(45)
BD = 7 units
(b)
[tex]\frac{adjacent}{hypotenuse} = cos(x)[/tex]
[tex]\frac{7}{BC}=cos(45)[/tex]
[tex]\frac{7}{cos(45)}= BC[/tex]
BC = 7√2 units
