What is the value of x?

enter your answer in the box.

x =

two lines slightly inclined with horizontal intersect at the midpoint forming an obtuse angle. the above obtuse angle is labeled left square bracket 2 left parenthesis x plus 10 right parenthesis right square bracket degrees. the below obtuse angle is labeled left parenthesis 3 x minus 30 right parenthesis degrees.

Answer : The value of 'x' is,

Step-by-step explanation :

From the given figure we conclude that, the given angles are vertically opposite angles.

That means, the vertically opposite angles are equal.

Now rearranging the terms, we get:

Therefore, the value of 'x' is,

d

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

-4, -2, 1, 4

domain = x values

range = y values
