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

Ilya [14]

Answer:

$Yearly = \$59.88$

Step-by-step explanation:

Given

$Monthly = \$4.99$

Required

Determine the yearly cost

To do this, we multiply the monthly subscription by 12

$Yearly = Monthly * 12$

$Yearly = \$4.99 * 12$

$Yearly = \$59.88$

<em>Hence, the yearly servics cost is $59.88</em>
