Δ = (8i)^2 - 4*(-25) => Δ = -36 +100 => Δ = 64 => x1 =(-8i + 8)/2 => x1 = -4i +4;
x2 = (-8i - 8)/2 => x2 = -4i-4; in this case, your solutions are complex conjugates.
Answer:
Step-by-step explanation:
All triangle must have angle values adding up to 180 degrees.First solve for y;
110+33+y=180
y=37 degrees
x is the opposite inverse angle of 33 degrees, it has an angle measure of 33 degrees.
z is equal to 110 degrees because it is opposite to that angle measure because all rhombi have 2 way symmetry.
First we need to find the slope of line k. Using the slope formula, we fill in accordingly:

. The slope is -3/2. The slope of a line that is perpendicular to line k will have the opposite sign (so, positive) and will be the reciprocal of the line k's slope (so, 2/3). You could also say, more "mathematically legal", that the product of the slopes of perpendicular lines is -1, but it's easier to just say that they are opposite reciprocals. The slope you're looking for is 2/3. Choice 3 above.
