Can someone help me with this problem pls
GREYUIT [131]

Answer:

my answer was 7.5

Step-by-step explanation:

    2

2b+3b-10

4b+3b-10

10-7b=3b fraction bar means divide so...

3b

__                       2

4b because... b-2b=4b and 8-4b=4b

3/4 =7.5 because 4 cant go into three so you add a decimal and a zero and move decimal up and 4 can go into 30 7 time which equals 28 and 30-28 is 2 add another zero and its 20 and 4 goes in 5 times which equals 20 and 20-20=0 so its 7.5 (i hope this helps ;)

Given that abcd is a rhombus, what is the value of x?
jeyben [28]

Answer:

A - 19.5

Step-by-step explanation:

A Rhombus is characterized by the diagonals meeting at a right angle. Therefore, the angle in the center is 90 degrees.

If you look at the bottom triangle, you know that the angles of a triangle add up to 180 degrees. You can say that all of the angles of the triangle added to 180 are:

(3x + 12) + (x) +(90) = 180 degrees

4x + 102 = 180 degrees    combining like terms

4x + 102 - 102 = 180 - 102

4x = 78

4x/4 = 78/4

x = 19.5 degrees
