Answer:

  • x = 25°

Step-by-step explanation:

Since BD is altitude, BD ⊥ AC

Therefore ∠ ADB = 90°

  • 3x + 15° = 90°
  • 3x = 90° -15°
  • 3x = 75°
  • x = 75°/3
  • x = 25°

Use completing the square to solve the equation x2+16x=−44 . First determine the number you must add to both sides of the equati
lilavasa [31]

Answer:

We will add 64 to both sides.

x=8±√20

Step-by-step explanation:

Here we are given the equation:

x^{2}+16x=-44

Now we take half of the coefficient of x and add it to x.

Coefficient of x is 16, half of 16 is 8.

Also we add square of 8 to both sides.

So new equation becomes:

x^{2}+16x+64=-44+64

Completing the square:

(x+8)^{2}=20

NOw let us  simplify it to get the value of x.

Taking square root on both sides:

x+8=+/-\sqrt{20}

Bringing 8 to the right side:

x=8±√20
