What is the height of an isosceles trapezoid, if the lengths of its bases are 5m and 11m, and the length of a leg 4m? (Please sh
Ivan

We have been given the measure of two parallel sides as 11 m and 5 m. And we are given one of the slanted sides as 4 m.

From the given information, we can find the base of one of the side triangles as 3 m.

Therefore, upon using Pythagorean theorem, we get the set up for height as

h^{2}=4^{2}-3^{2}=7

h=\sqrt{7}

Therefore, height of the required figure is \sqrt{7} m

An integer 2 less than 4 times another. If the product of the two integers is 90 then find the integers
levacccp [35]

Let x and y be the 2 integers.

Then  x = 4y - 2

and xy = 90

Substitute for x in the second equation:-

(4y - 2)y = 90

4y^2 - 2y - 90 = 0

2y^2 - y - 45 = 0

(2y + 9)(y - 5) = 0

so y = 5    ( as it is an integer)

and x =  = 90/5 = 18


Answer:-  The 2 integers are 5 and 18.
