Alona [7]

Answer:

40 ft

Step-by-step explanation:

If two polygons are congruent to one another, therefore, it implies that the angles and sides of one is congruent to the corresponding sides and angles of the other.

Given that ABCD is congruent to EFGH, therefore:

CD ≅ GH

Since CD = 40 ft, therefore, GH will be 40 ft.

Solve for x please for 10 points

Ira Lisetskai [31]

Answer:

$\frac{x-2}{2+1}=\frac{4x-5}{3}$

$\frac{x-2}{3} =\frac{4x-5}{3}$

$3*\frac{x-2}{3} =\frac{4x-5}{3}*3$

$x-2=4x-5$

$x-2+5=4x-5+5$

$x-x+3=4x-x$

$3=3x$

$\frac{3}{3} =\frac{3x}{3}$

$1=x$

Step-by-step explanation:

your answer is B
