What is the measure of x
mixer [17]

Answer:

x=76 degrees

Step-by-step explanation:

< dij + < jih = 180   straight line

< dij + 107 = 180

subtract 107 from each side

< dij = 73


<jdi + < dij + <idj = 180  triangle

31 + 73 + < idj = 180

combine like terms

104+ < idj = 180

subtract 104 from each side

< idj = 76

<idj = < ajf   vertical angles

76 < ajf

<ajf = x

x=76 degrees

Find x and the length of each segment <br> s<br> 13<br> T <br> 6<br> U<br> 2x-18<br> y<br> 4x-29
emmasim [6.3K]

Answer:

x = 15, UV = 12, SV = 31

Step-by-step explanation:

13 + 6 + (2x - 18) = 4x - 29

2x + 1 = 4x - 29

2x = 30

x = 15

UV = 2x - 18 = 2*15 - 18 = 30 - 18 = 12

SV = 4x - 29 = 4*15 - 29 = 60 - 29 = 31
