Pls Help Me!!!!!!!!!!!Solve For The Variable "x" In This Example

Answers

Answer 1

Answer:

x=9

Step-by-step explanation:

these are vertical angles, so they equal eachother!

12x-3=105

move three to the other side of the equals sign

12x=108

divide both sides by 108

x=9

Answer 2

Answer: x=9

Step-by-step explanation:

These angles are equal, so you can set 105 equal to 12x-3. Add 3 and divide by 12 to get x=9.

Tell whether the angles are adjacent or vertical. Then find the value of x.

Answers

Answer:

Adjacent angles. x = 55

Step-by-step explanation:

Adjacent angles are angles that are right next to each other, sharing one side.

Since that is a right angle (90º):

X + 35 = 90

X + (35-35) = 90 - 35

X = 55

Hope this helps! Have a great day!

Answer:

Adjacent, X= 55

Step-by-step explanation:

90-35= 55

x=11 should be the answer lmk if so

Answer:

x = 18

Step-by-step explanation:

m∠1 & m∠3 are vertical angles. By definition of vertical angles, their measurements will be the same.

It is given that:

m∠1 = 4x - 14

m∠3 = 58°

Set the two angles equal to each other:

4x - 14 = 58

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, add 14 to both sides of the equation:

4x - 14 (+14) = 58 (+14)

4x = 72

Next, divide 4 from both sides of the equation:

(4x)/4 = (72)/4

x = 72/4 = 18

18 is your answer for x.
