Answer:

Step-by-step explanation:
<u><em>The complete question is</em></u>
Given the quadrilateral is a rectangle, if LO = 15x+19 and QN = 10x+2 find PN
see the attached figure to better understand the problem
we know that
The diagonals of a rectangle are congruent and bisect each other
so

substitute the given values

solve for x

Find the length of PN
Remember that
----> diagonals of rectangle are congruent

substitute the value of x

therefore

Answer:
Height is 3
Step-by-step explanation:
4.24 x 4.24 x 6
Right triangle base = a + b + c
a^2 + 3^2 = 4.24^2
= a^2 + 9 = 17.98
We cross out b to subtract.
a^2 = 17.98 - 9
a^2 = 8.98
We then square √a^2 = √8.98
a = 2.996
We round up a = 3
We have found the height is 3
