In rhombus ABCD, the diagonals AC and BDintersect at E. If AE=5 and BE=12, what is thelength of AB?
hram777 [196]

Diagonals that bisect each other are perpendicular and form a right angle.

AEB is a right triangle.

We can apply the Pythagorean theorem:

c^2 = a^2+b^2

Where c is the hypotenuse (longest side) and a and b the other 2 legs.

Replacing:

AB^2 = AE^2+BE^2

AB^2 = 5^2+12^2

AB^2 = 25+144

AB^2 = 169

AB=√169 = 13

Lenght of AB= 13

What’s the linear equation in slope intercept form to (-3,7) and (6,-8)?
Aleonysh [2.5K]
Y= -5/3x + 2

To find slope:
-8-7 / 6 - (-3) = -5/3

Plug in x and y from one of the points to the equation to find b

7 = -5/3 (-3) + b

B = 2

Put it all together:

y = -5/3x + 2
