A square (or in this case parallelogram) has a measure of 360 degrees. In parallelograms, the opposite angles are congruent therefore: <A = <C and <B = <D. To solve the problem you would do 360 - (<A + <C) then divide by (1/2) since <B and <D are the same. So, 360 - 140 = 220; 220/2= 110. In conclusion, <D = 110. Answer Choice: C

What is the value of x?<br><br> Enter your answer in the box.<br><br> x =
andreev551 [17]

The two angles form a straight line which equals 180 degrees:

10x-20 + 6x + 8 = 180

Combine like terms:

16x -12 = 180

Add 12 to both sides:

16x = 192

Divide both sides by 16:

X = 192/16

X = 12

127 pounds to kilograms?​
shusha [124]

For this case we must make a conversion from pounds to kilograms.

By definition we have to:

1 kg equals 2.20462 pounds. Making a rule of three we have:

2.20462 pounds ---------------> 1 kg

127 pounds -----------------------> x

Where "x" represents the amount of kg.

x = \frac {127 * 1} {2.20462} = 57.6062

Thus, 127 pounds represent 57.61 kilograms.

Answer:

57.61 kilograms.
