Answer:
10) x=15.9 11) x=17.5
Explanation:
round to the nearest tenth is to one decimal place
to find the hypotenuse (11):
x = square root of one side squared plus the other side squared
x= square root 9^2 + 15^2
x= square root 81 + 225
x= square root 306
x= 17.5
to find a side (10):
x = square root of the hypotenuse squared minus the known side squared
x= square root 17^2 - 6^2
x= square root 289 - 36
x= square root 253
x= 15.9
