you know the angle is formed 90 degree.
and the sum of the angel of traingel is 180 degree. so.. let's begin.
180-90=90.
90÷2 =45 .
so angel c is 45 degree.

Answer:
=> 62.73°
Step-by-step explanation:
In Δ ABC, for angle B :-
- perpendicular is AC
=> AC = 8
∴ => perpendicular = 8
- hypotenuse is AB
=> AB = 9
∴ => hypotenuse = 9
We know that,
sin θ = perpendicular/ hypotenuse
sin B = 8/ 9
sin B = 0.88
sin B = 0.88 for angle B = 62.734°
On rounding off to the nearest hundredth
B = 62.73°
