Ответ:
m∡A = 41.4°
m∡B = 48.6°
m∡C = 90°
a = 3![\sqrt{7}](/tpl/images/1339/2100/69133.png)
b = 9
c = 12
Step-by-step explanation:
to find the length of side 'a' I used the Pythagorean Theorem to get:
a² + 9² = 12²
a² + 81 = 144
a² = 63
a =
which equals ![\sqrt{9}](/tpl/images/1339/2100/46729.png)
which is 3![\sqrt{7}](/tpl/images/1339/2100/69133.png)
to find m∡B I found the arcsin(B) = 9/12 to get 48.6
to find m∡A I subtracted the sum of 90 + 48.6 from 180°
