Not trying to fell test help me out

14. 32.9

15. 8.5

16. 45°

Step-by-step explanation:

14. a² + b² = c²

11² + 31² = c²

121 + 961 = c²

√1082 = c

32.9 = c

15. a² + b² = c²

c² - b² = a²

19² - 17² = a²

361 - 289 = a²

√72 = a

8.5 = a

16. x = 45°

Hope that is correct... have a good day!

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
