Given rs || qp, what is the value of x?

myrzilka [38]

In the given figure,

Angle 108° + 12x = 180°

because they for pair of co- interior angles which are supplementary.

so,

$12x + 108\degree = 180\degree$

$12x = 180\degree - 108\degree$

$12x = 72\degree$

$x = \dfrac{72\degree}{12}$

$x = 6\degree$

hence , value of x = 6°

madam [21]

Answer: 4:20

Step-by-step explanation:

60 lbs can be divided into three groups, in this case the bags of sand, so 60 divided by 3 is 20.

Now you have the 8 lbs left. It gets divided into two groups/bags so you would do 8 divided by 2 is 4.

Then for your ratio it is cement to sand which is 4:20. You can write the ratio however way you want or what is required by the question.(fraction bar, ‘to’, or colon ‘:’ )

Hope this helps!
