Answer:
x = 15
UV = 12
SV = 31
Step-by-step explanation:
#3) ST + TU + UY is the same length as the line below
which is labeled as '4x-29'; so we can use this equation to find 'x':
13+6+2x-18 = 4x-29
combine 'like terms':
1 + 2x = 4x - 29
subtract '2x' from each side to get:
1 = 2x - 29
add 29 to each side to get:
30 = 2x
30/2 = x
15 = x
UV = 2x-18 so substitute 15 in for 'x' to get:
UV = 2(15)-18 = 30-18 = 12
UV = 12
SV = 13 + 6 + 12 which equals 31
