Step-by-step explanation:

The formula tells you what to do.

t = 3

A0 = 25

A(t) = ?

A(3) = 25 * (1/2)^3

A(t) = 25 * 1/8

A(t) = 25/8

A(t) = 3.125

Please help me asap!

Answer: 1. ∠A= 80.75° 2. 41.79 $cm^2$

Step-by-step explanation:

Since, According to the sines low,

$\frac{sin A}{CB} = \frac{sin C}{AB}$

Here, CB= 4.1 cm, AB = 3.3 and ∠ C = 52.6°

$\frac{sin A}{4.1} = \frac{sin 52.6}{3.3}$

⇒ $sin A = 4.1\times\frac{sin 52.6}{3.3}$

⇒ $sin A =0.98699998308$

⇒ A = 80.75°

2. Since, the area of the given figure = Area of the rectangle having dimension 8.3 × 4.2 + Area of the half square of radius 2.1

=34.86 + 6.93

= 41.79 square cm
