The answer I got is (-6,-2) the x value is -6
Answer:
Let's use the slope-intercept form of the equation of a line describe the slope and the y-intercept:
y = mx + b where m=slope and b=y-intercept
It's an equilateral triangle, therefore
AB = BC = BA
We have the equation:
<h3>Answer: BC = 3</h3>
Answer:
The area of square in terms of x = 16x² -24x + 9
Step-by-step explanation:
It is stated in the question that the length of a square = 4x - 3
Formula to find the area of the square is
<h2 /><h2>Area = length²</h2><h2 />
Area = ( 4x - 3 )²
<em>by using ( a - b )² = a² + b² - 2ab</em>
here a = 4x and b = -3
So,
(4x)² + (-3)² - 2(4x)(3)
16x² + 9 - 2(12x)
16x² + 9 - 24x
16x² -24x + 9
The area of square in terms of x = 16x² -24x + 9
x = 2(180 - x) - 12
3x = 348
x = 116
The measure of the angle is 116 degrees.
