vodomira [7]

Answer:

See below in bold.

Step-by-step explanation:

1.  x/8 = 15/24

Cross multiplying:

24x = 8*15

x = (8*15)/24

x = 5.

2.   5/6 = 35/x

5x = 6*35

5x = 210

x = 210/5

x = 42.

3.<em>  </em>18/42

Divide top and bottom by 6:

18 / 6 / 42/6

= 3/7.

4.  15/75

Divide top and bottom by 15:

= 1/5.

Given that ABCD is a rhombus, what is the value of x?
SashulF [63]

Answer:

B

Step-by-step explanation:

A rhombus is divided into four congruent triangles. The two given angles are complementary, meaning they add up to 90 degrees. Set up an equation:

(4x-25)+x=90

4x-25+x=90   Take out the parentheses

5x-25=90   Combine like terms

5x=115   Add 25 to both sides so as to isolate the variable

x=23   Divide both sides by 5
