Here an easy question for points it’s a few but they easy

See explanation

Step-by-step explanation:

3.) 140 and its supplementary angle form a straight line, basically, they sum up to 180°. That angle is y

y + 140 = 180

Subtract both sides by 140

y = 40°

Seems both angles are congruent since they have the same label.

y + x + x = 180°

40 + 2x = 180

Subtract both sides by 40

2x = 140

Divide both sides by 2

x = 70°

4.) The missing angle = y

2x - 14 + 3x + 2 + y = 180

5x - 12 + y = 180

Subtract 5x from both sides

-12 + y = - 5x + 180

Add 12 to both sides

y = -5x + 180 + 12

y = -5x + 192

3x + 2 + 2x - 14 - 5x + 192 = 180

3x + 2x - 5x + 2 - 14 + 192 = 180

0 + 180 = 180

180 = 180

That's correct I guess.

5.) Missing angle = y

2x + 8 + 5x + y = 180

7x + 8 + y = 180

Subtract 7x from both sides

8 + y = -7x + 180

Subtract 8 from both sides

y = -7x + 180 - 8

y = -7x + 172

2x + 8 + 5x - 7x + 172

2x + 5x - 7x + 8 + 172 = 180

0 + 180 = 180

180 = 180

I.. think that's correct..?

6.) Missing angle = y

134 + y = 180

Subtract 134 from both sides

y = 46°

x + 46 + 22 = 180

x + 68 = 180

Subtract 68 from both sides

x = 112°

#4 and #5 were honestly sooo confusing. I just did whatever but I hope this is correct lol.
