How do you find the value for x? <br> Find the value of x ?
bogdanovich [222]

Answer:

x = 27

Step-by-step explanation:

Both angles together form 180 degree.

Set your formula up as

180 = (5x+2) + (x + 16)

180 = 5x + 2 + x + 16

180 = 6x  + 18

180 - 18 = 6x

162 = 6x

162/6 = x

27 = x

PLEASE HELPTH ME (MODERATORS STOP I REPEAT STOP REMOVING MY QUESTIONS BRO)
kompoz [17]

Answer:

X=75

Y=110

Step-by-step explanation:

A straight line is 180, so add the equations that make a line and set them equal to 180

x+20+x+10=180

Combine like terms

2x+30=180

Subtract 30 from both sides

2x=150

Divide by 2

X=75

Same for y

y+y-40=180

2y-40=180

Add 40 to both sides

2y=220

Divide by 2

Y=110
