Answer:
30.75 ft or 30 ft after rounding to nearest 10th
Step-by-step explanation:
the length of y can be calculated using the Pythagoras Theorem
which is a²+b²=c²
a is 17
b is 28
c is unknown
17²(a²) is 289
28²(b²) is 784
784+289=1073
c²=1073
the value of c is in square/²
so, we take the square root on both sides
the square/² on c will cancel the square root
the square root of 1073 is 30.75
rounded to nearest tenth is 30
we assumed y as c
therefore c= 30.75 ft or 30 ft
