Question

Phythagorean theorem help me plsss

Answer 1

d = 5 m

Explanation:

The diagonal divides the rectangle into 2 right triangles with legs 3 and 4 and hypotenuse h

Using Pythagoras' identity in one of the right triangles, then

d² = 3² + 4² = 9 + 16 = 25 ( take the square root of both sides )

d =
`√(25)` = 5

Answer 2

5

Explanation:

We know that a^2+b^2=c^2 from the Pythagorean theorem where a and b are the legs and c is the hypotenuse

4^2+3^2 = c^2

16+9 = c^2

25 = c^2

Taking the square root of each side

sqrt(25) = sqrt(c^2)

5 =c
