Answer:Its A

Step-by-step explanation:Collinear points are the points that lie on the same straight line or in a single line. If two or more than two points lie on a line close to or far from each other, then they are said to be collinear, in Euclidean geometry. ( this is from g.o.o.g.l.e but i put my sense into this question and a is the only one that makes sense )

The weight of 10 identical samples of a substance is 0.01 pounds what is the weight of 100 samples

valentina_108 [34]

Hola!!

If 10 = 0.01
then you could divide 100 by 10 which is 10
So then you multiply 0.01 by 10 which is <span>0.1

So the answer is 0.1

Solve for x. <br> (parallelogram)

victus00 [196]

The value of x is 55°

Step-by-step explanation:

Given figure is a parallelogram.

In a parallelogram, the opposite sides are equal and parallel and the opposite angles are equal.

This means that,

in the given parallelogram

m∠A=m∠C=x°

m∠B=m∠D=(2x+15)°

The sum of interior angles of a parallelogram is 360 degrees.

So,

m∠A+m∠B+m∠C+m∠D=360°

Putting the values of angles

$x+(2x+15)+x+(2x+15)=360\\x+2x+15+x+2x+15=360\\6x+30=360\\Subtracting\ 30\ from\ both\ sides\\6x+30-30=360-30\\6x=330\\Dividing\ both\ sides\ by\ 6\\\frac{6x}{6}=\frac{330}{6}\\x=55$
