Answer:
AC = 6
Step-by-step explanation:
given ∠A = ∠C then triangle is isosceles with BC = AB, hence
3x - 8 = x + 4 ( subtract x from both sides )
2x - 8 = 4 ( add 8 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
⇒ AC = x = 6
20%
90 - 75 = 15
15 ÷ 75 = 0.2
0.2 x 100% = 20%
0,
The range of f(x) is [0,∞),
