What is the value of x and the last answer is 30

x=30

Step-by-step explanation:

The two angles are on a straight line, so they are supplementary. They add to 180 degrees.

4x+20+40=180

Combine like terms

4x+60=180

Subtract 60 from both sides

4x+60-60=180-60

4x=120

Divide both sides y 4

4x/4=120/4

x=30

30°

Step-by-step explanation:

The two angles: 4x + 20° and 40° are supplementary.

This means that when added, they will equal 180°. I know that these angles are supplementary because they form a straight line.

Let's write this as an equation:

4x +  20° + 40° = 180°

Solve:

4x + 20 + 40 = 180

Combine like terms (add 20 and 40):

4x + 20 + 40 = 180

4x + 60 = 180

Subtract 60 on both sides:

4x + 60 = 180

     -60     -60

4x = 120

Divide by 4 on both sides:

4x = 120

/4     /4

x = 30

Therefore, the value of x is 30 degrees.

segment bisector

step-by-step explanation:

line segment bisector. definition: a line, ray or segment which cuts another line segment into two equal parts. try this drag one of the orange dots at a or b and note the the line ab always divides the line pq into two equal parts.

mark brainliest!

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93
