Answer:

m∠C = 90°

m∠A  = 25°

BC = 3.803564355666

AC = 8.15677008333

Step-by-step explanation:

ABC is a right triangle at C then

m∠C = 90°

m∠A = 90 - m∠B = 90 - 65 = 25°

……………………………

[tex]\cos \left( 65\right) =\frac{BC}{9}[/tex]

[tex]\Longrightarrow BC=9\times \cos \left( 65\right) =3.803564355666[/tex]

……………………………

[tex]\sin \left( 65\right) =\frac{AC}{9}[/tex]

[tex]\Longrightarrow AC=9\times \sin \left( 65\right) =8.15677008333[/tex]
