Answer:
x = 55
Step-by-step explanation:
(x - 14) + 99 + 220 = 360
x - 14 + 99 + 220 = 360
x - 14 + 319 = 360
x + 305 = 360
x = 360 - 305
x = 55

Answer:
ST = 4
Step-by-step explanation:
A segment joining the midpoints of 2 sides of a triangle is half the length of the third side.
ST =
PQ substitute values
- 32 + 9x =
(- 5x + 28) ← multiply both sides by 2 to clear the fraction
- 64 + 18x = - 5x + 28 (add 5x to both sides )
- 64 + 23x = 28 ( add 64 to both sides )
23x = 92 ( divide both sides by 23 )
x = 4
Then
ST = - 32 + 9x = - 32 + 9(4) = - 32 + 36 = 4
