Answer:
12.8
Step-by-step explanation:
let the missing length be x
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , then
x² = 10² + 8² = 100 + 64 = 164 ( take square root of both sides )
x = [tex]\sqrt{164}[/tex] ≈ 12.8 ( to the nearest tenth )
Answer:
12.8
Step-by-step explanation:
lets keep the missing length as c
10^2+8^2=c^2
100+64=c^2
164=c^2
now find the square root of 164=12.8062485=
now round the the nearest tenth (the first one after the decimal)
=12.8
hope this helps
