Answer:

24°

Step-by-step explanation:

Supplementary angles: angles that add up to 180°

Thus, ∠A + ∠B = 180°

=> (x + 6)° + (7x + 30)° = 180°

=> 8x + 36 = 180

=> 8x = 180 - 36

=> 8x = 144

=> x = 18

∠A = (18 + 6)° = 24°

Answer:

$P(x) = -0.25x^2 + 42x - 90$

Step-by-step explanation:

Given

$C(x) = -17x + 90$

$R(x) =- 0.25x^2 + 25x$

Required

Determine the profit function.

Profit function is calculated as thus:

$P(x) = R(x) - C(x)$

So, we have:

$P(x) = -0.25x^2 + 25x -(-17x + 90)$

$P(x) = -0.25x^2 + 25x + 17x - 90$

$P(x) = -0.25x^2 + 42x - 90$
