2x + x = 135
3x = 135
x = 135 /3
x = 45

1. I'm not completely sure, but these angles seem to be complementary, meaning they add up to 90°. Since 75° + x = 90°, x = 15°.
2. These lines seem to be parallel. ∠4 ≅ ∠1 because they are vertical angles, ∠5 ≅ ∠1 because they are corresponding angles, and because ∠8 ≅ ∠4 (corresponding angles), ∠8 ≅ ∠1 as well. The final answer is ∠4, ∠5, and ∠8. Hope this helps!
Answer: f·g(x) = 12x³ - 6x² - 10x +5
fog(x) = 24x² - 24x + 1
<u>Step-by-step explanation:</u>
f(x) = 6x² - 5 g(x) = 2x - 1
f·g(x) = (6x² - 5)(2x - 1)
= 6x²(2x - 1) - 5(2x - 1)
= 12x³ - 6x² - 10x + 5
fog(x) = f(2x-1)
= 6(2x - 1)² - 5
=6(4x² - 4x + 1) - 5
= 24x² - 25x + 6 - 5
= 24x² - 25x + 1
