1 answer:

8 0

let 'N' be a substitute for a number example 1/3(n)=n-12 then now we can multiply by 3 so we can get it n=3n-36 now get n onto the same side of the equation so we get 2n=36.after that divide by 2 we get n=18.

Calculate the length of the unknown side of this right angled triangle

azamat

Answer:

12.04

Step-by-step explanation:

Well to solve for the unknown side "c" we need to use the Pythagorean Theorem formula,

$a^2 + b^2 = c^2$

We already have a and b which are 8 and 9 so we plug them in.

$(8)^2 + (9)^2 = c^2$

64 + 81 = c^2

145 = c^2

c = 12.04 rounded to the nearest hundredth.

Thus,

the unknown side is about 12.04.

Hope this helps :)
