Answer: (x+8)²
Step-by-step explanation:
When you complete the square, the factor is squared. You want to first factor the equation.
x²+16x+64=0
(x+8)(x+8)=0
Now that we have factored the equation, we can put in into squares.
(x+8)²
The area of triangle ABC is the amount of space on the triangle
The area of the triangle is 54.84 square units
<h3>How to determine the area of triangle ABC</h3>
Start by drawing the triangle (see attachment)
Next, calculate the measure of angle B using the following tangent ratio
This gives
Take the arc tan of both sides
Multiply by 2
Next, calculate the length of side AD using the following equation
This gives
The area of the triangle is then calculated as:
This gives
Hence, the area of the triangle is 54.84 square units
