HELP!! i need this done as quickly as possible!! this is a make or break for me.

Answer 1

1) By Pythagoras theorem

16² = x² + (√65)²

256 = x² + 65

x² = 256-65

x² = 191

x=√191

x=13.82 or 13.8 ft

2) 15²=x²+10²

225=x²+100

x²=225-100

x²=125

x=√125

x=11.18 or 11.2km

3) 12.36 or 12.4 cm

4) 8.36 or 8.4 mi
