Answer:

The measure of the 3 angles is 36.9, 53.1 and 90 degrees.

Step-by-step explanation:

5^2 = 3^2 + 4^2 so , by the inverse of Pythagoras Theorem, this is a right angled triangle so one angle is 90 degrees.

We can find the other 2 angles using trigonometrical ratios.

One angle will have a sine of 3/5 and the other a sine of 4/5.

So the angles are arcsin 3/5 = 36.9 degrees and the other is arcsin 4/5 = 53.1 degrees.

What is the area of the shaded region and the circle inside?

$r=20,1m+13,2m=33,3m$
$A_1=\pi r^2$
$A_1=33,3^2\pi$
$A_1=1108,89\pi$

What is the area of the circle inside?

$A_2=20,1^2\pi$
$A_2=404,01\pi$

What is the area of the shaded region?

$1108,89\pi -404,01\pi =704,88\pi$
$704,88\pi \approx 704,88*3,14\approx 2213,3232\approx \underline{2213,32}$

The answer: 2213,32 :)
