Darla is building a new desk. to make sure she had made a square corner, she measures 3ft. from the corner along one edge and 4 ft. from the corner along the other edge. how long should the diagonal be between those two ppoints if the corner is a right angle?

The answer is 5 ft.

Step-by-step explanation:

First, Darla measures 3 ft from the corner along one edge: let’s assume the measurement is from west (corner A) to east (new corner B).

Second, Darla measures 4 ft from the corner along the other edge: the measurement is from the new corner B, northwards to another new corner C.

The length of the diagonal will be the distance between corner A and new corner C = hypotenuse = x .

We know that if the corner is a right angle corner, then we will have a right-angled triangle where the square of the hypotenuse = sum of the squares of the opposite and adjacent sides:

the adjacent side = 3 ft

the opposite side = 4 ft

Therefore, x² = 3² + 4² = 25

x = square root of 25 = 5 ft

Length of the diagonal = x = 5 ft .

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
