Work out the value of x.Need answer soon :) ​

Mathematics
1 answer:
german3 years ago
6 0

Answer:

x+20

Step-by-step explanation:

As we can see n the diagram, there are parallel traversals and one line, and the two angles given are same-side interior angles. We know that when there is parallel traversal, and we have same side interiors, the sum of the measure of the two angles are supplementary. Supplementary means 180 degrees, or a straight line.

So we plug everything in and we have  4x+5x=180 degrees

4x+5x=9x, so 9x=180

We divide by 9 on both sides to get the value of x, which is 20

Hope it helps!

raketka [301]

Answer:

n = -14

Step-by-step explanation:

-3(n+9)=15

Distribute -3 to (n+9):

-3n - 27 = 15

Add 27 to both sides:

-3n = 42

Divide both sides by -3:

n = -14

Which statements are true regarding the diagram?
Murrr4er [49]

As <GNJ & < JNK form a striaght angle

And < JNK = 90°

So <GNJ = 90°

So <GNH + <HNJ = 90°

So GNH & HNJ are complimentary is true.

As JNK and KNL do not form a straight angle.

So <JNK +< KNL is not equal to 180°.

Hence JNK and KNL are supplementary is not true.

As <KNM & < JNK form a straight angle

And < JNK = 90°

So <KNM = 90°

So <KNL + <LNM = 90°

So KNL & LNM are complimentary is true.

As HNL makes a straight angle

And so

mHNK + mKNL = 180° is true

As MNG itself is 90°

So

<MNG + <GNH cannot be 90° hence this is false.

Plotting is the place the dots belong to?

If you want to do a positive of which is like (x,5) then you go to in between the right top and bottom or x axis where the positives are and count, if the (2,y) is positive you count and go up if y is a negative then you count down how many number there is.

Let’s use (1,-1) first you go into the x-axis, one is a positive so you go to one in there, and go down one or to -1 bc the -1 is a negative and the digit is 1. ( I hope it made sense, if u need more help u can tell me.)
