By the Addition Principle of Equality, I would add 3.4 to both sides of the equation to get rid of the constant term -3.4 on the right-hand side.

12.7 + 3.4 = j - 3.4 + 3.4
16.1 = j

So, j is equal to 16.1.

12.7 = j - 3.4

We're simply just trying to get j by itself.

So, add 3.4 to both sides.

12.7 + 3.4 = j

Simplify.

16.1 = j

So, j = 15.1

the hypotenuse of a right angled triangle is 26cm, if the other side 24cm. find the length of the third side

weeeeeb [17]

You need Pythagorean theorem for this.

a² + b² = c², where c is the hypotheneus and a and b are the sides of the right triangle.

24² + x² = 26²

x² = 676-576

x = ±√100

x = 10 (-10 is rejected because length of triangle cannot be a negative number)
