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.

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's find the Radius ~

$\qquad \sf \dashrightarrow \: area = \frac{ \theta}{360} \times \pi {r}^{2}$

$\qquad \sf \dashrightarrow \: 80= \frac{ 72}{360} \times \pi {r}^{2}$

$\qquad \sf \dashrightarrow \: {r}^{2} = \frac{80 \times 360}{72 \times \pi}$

$\qquad \sf \dashrightarrow \: {r}^{2} = \frac{80 \times 5}{ \pi}$

$\qquad \sf \dashrightarrow \: {r}^{} = \sqrt\frac{400}{ \pi}$

$\qquad \sf \dashrightarrow \:r = \frac{20}{ \sqrt{\pi} }$

$\qquad \sf \dashrightarrow \:r \approx 11.28 \: ft$

I hope you understood the whole procedure, let me know if you have doubts ~
