Find the exact length of the third side .

The length of unknown third side of right triangle can be found by using Pythagoras theorem. a = √(c^2 - b^2) is the formula to find the length a:, b = √(c^2 - a^2) is the formula to find the length b: and c = √(a^2 + b^2) is the formula to find the length c:.

Step-by-step explanation:

a=9.8

Step-by-step explanation:

a(2)+2(2)=10(2)

2×2=4 10×10=100

subtract 4 from 4 and 100

a(2)=9.6

use the two buttons on the scientific caculator. Click 2nd, then click x2(close to bottom left)

you will get a bunch of numbers only put down the first 3. (9.79)

ROUND THIS

9.79=9.8

a=9.8
