PLEASE HELP i need this for today at 4

Answer 1

Step-by-step explanation:

Work out the value of x.

#12

The angles are supplementary as same side interior angles, sum to 180°:

• x + x - 26 = 180
• 2x = 206
• x = 103

#13

The angles are corresponding, hence congruent:

• 3x - 5 = x + 55
• 3x - x = 55 + 5
• 2x = 60
• x = 30

#14

The angles are supplementary as same side interior angles, sum to 180°:

• 2x + 24 + x = 180
• 3x = 180 - 24
• 3x = 156
• x = 52

#15

The angles are corresponding, hence congruent:

• 4x - 12 = 3x + 6
• 4x - 3x = 6 + 12
• x = 18

#16

Corresponding with the right angle:

• 4x + 12 = 90
• 4x = 78
• x = 19.5

#17

Vertical angle of the bottom angle is supplementary with the top angle:

• 2x + 12 + 3x + 23 = 180
• 5x + 35 = 180
• 5x = 145
• x = 49

Answer 2

Answer:

It is given

4x+3y=24

We can also write it as

3y=24−4x

 y=324−4x

Substituting x=0 in the given equation

 y=324−4(0)

 So we get 

 y=324

 By division 

 y=8 

 Substituting x=3 in the given equation 

 y=324−4(3)

 So we get

 y=312

 BY division 

 y=4
