(BRAINLYST FOR ANSWER IF CORRECT) What is the value of c?<br> c+15°<br> c–16°<br> c–18°
asambeis [7]

Answer:

c = 49°

Step-by-step explanation:

Inside of the triangle angles:

  • c–18°
  • c–16°
  • 180°-(c+15) → -c+165

these angles sum up to total 180° angle

-c+165+c-16°+c–18° = 180

c +131 = 180

c = 180° - 131°

c = 49°

use a method of completing the square in order to rewrite the function f(x)=x^2+5x-2 in vertex form, f(x)=a(x-h)^2+k where (h,k)
yuradex [85]
      f(x) = x² + 5x - 2
f(x) + 2 = x² + 5x - 2 + 2
f(x) + 2 = x² + 5x
f(x) + 2 = x(x) + x(5)
f(x) + 2 = x(x + 5)
      f(x) = x(x + 5) - 2
   (h, k) = (-5, 2)

Solve for a: 3a+4bc-d=5a-8j
krek1111 [17]

3a + 4bc - d = 5a - 8j

<em><u>Add d to both sides.</u></em>

3a + 4bc = 5a - 8j + d

<em><u>Subtract 4bc from each side.</u></em>

3a = 5a - 8j + d - 4bc

<em><u>Subtract 5a from both sides.</u></em>

-2a = -8j + d - 4bc

Divide both sides by -2

a = \frac{(-8j -4bc + d)}{-2}
