Answer:

$a=56.4\degree$

Step-by-step explanation:

Let $a$ be an acute angle.

To solve: $\sin(a)=0.8325$ , we take the sine inverse of both sides to obtain:

$\sin^{-1}(\sin(a))=\sin^{-1}(0.8325)$

Recall composition property of a function and its inverse function.

$f^{-1}(f(x))=x$

We apply this property to the left hand side to obtain;

$a=\sin^{-1}(0.8325)$

We now use our scientific calculator to obtain;

$a=56.3564115\degree$

We round to the nearest tenth to obtain;

$a=56.4\degree$

Answer:

aₙ = 1/2 x aₙ₋₁ n≥2

Step-by-step explanation:

aₙ = 1/2 x aₙ₋₁ n≥2

a₁ = 64

a₂ = 1/2 x 64 = 32

a₃ = 1/2 x 32 = 16
