Answer:
BC = 23
Step-by-step explanation:
Since ∠ A = ∠ C then the triangle is isosceles with AB = BC, that is
3x + 14 = x + 20 ( subtract x from both sides )
2x + 14 = 20 ( subtract 14 from both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Thus
BC = 3x + 14 = 3(3) + 14 = 9 + 14 = 23
55 – 5q > 4(7–9)
4(-2)
55- 5q > -8
-5q > -63
q=12.6
Answer: its 49
