In a certain right triangle, the two sides that are perpendicular to each other are 4.30m and 7.40m. What is the length of the third side of the triangle?

a squared + b squared = c squared...u can do the rest!

Solve the Pythagorean theorem: a-squared + b-squared = the (unknown side)-squared : where a and b are the known sides and the (unknown side) is called the *hypotenuse of the right triangle with "legs" a & b. Do you home work. But if you don't have a calculator do it by hand calculation since a-squared= aXa=4.3X4.3. etc

8.56m
As with any right triangle, the length of the hypotenuse squared is equal to the sum of the squares of the opposite two sides -- a^2 + b^2 = c^2
4.3^2 +7.4^2 = c^2
18.49+54.76= c^2
c = sqrt 73.25 = 8.56

What's a RIGHT triangle?
Hypotenuse = Sqrt(4.3^2+7.4^2)
about 8.56

there is pythagores theorem that says a^2+b^2=c^2
a and b being the two sides that are perpendicular to each others.
in our case that means
4.30^¨2+7.40^2=x¨2
x=sqrt(4.3^2+7.4^2)
x=8,56

sqrt(4.3^2+7.4^2) = 8.5586 = 8.6 rounded to the same accuracy as the two sides.

a squared + b squared = c squared
or 4.3 squared + 7.4 squared = c squared
or 18.49 + 54.76 = 73.25
square root of 73.25 = 8.56
