Answer:

the answer is x = 7

Step-by-step explanation:

1) replace the x with 7

2) 7 + 16 = 23

3) 4(7) = 28

4) 28 - 5 = 23

they're both equal as perpendicular angles should be!

What is the answer to this??

Answer:

x=3

z=65

Step-by-step explanation:

6x+97 and 14x+73 are vertical angles which means they are equal

6x+97= 14x+73

Subtract 6x from each side

6x-6x+97= 14x-6x+73

97 = 8x +73

Subtract 73 from each side

97-73 = 8x+73-73

24 = 8x

Divide each side by 8

24/8 = 8x/8

3 = x

Now we need to find z

6x+97 and z are supplementary angles which means they add to 180

6x+97 +z = 180

6(3) +97 +z = 180

18+97+z=180

Combine like terms

115+z = 180

Subtract 115 from each side

115-115 +z=180-115

z = 65
