Answer:

1. x = 5

Step-by-step explanation:

The Trapezoid Midsegment Theorem states that a line segment connecting the midpoints of the legs of the trapezoid is parallel to the bases, and equal to half their sum.

In this problem you can see that 5x - 1 is the midsegment of the trapezoid, so using the rule:

$(21 + 27) / 2 = 5x -1$

solve:

$48/2 = 5x-1\\24 = 5x - 1\\25 = 5x\\x= 5$

2. Diagonals are congruent

You can see in this picture that the diagonals are not always congruent:

Multiply. Write your answer as a fraction in simplest form. 5/2*3/10

kherson [118]

(5/2)(3/10)=(5*3)/(2*10)=15/20=3/4

Or

(5/2)(3/10)= (5)(1/2)(3)(1/10)=(5)(3)(1/2)(1/10) =(5*3)/(2*10)=15/20=3/4

Or

(5/2)(3/10)=(5)(0.5)(3)(0.1)=(2.5)(3)(0.1)=(7.5)(0.1)=.75=3/4

All of these work, but the first one is simplest
