ERROR ANALYSIS. Sandra drew the triangle. Rika said that the lengths couldn’t be correct. With which student do you agree? EXPLAIN your answer.
Rika is correct, as the law of sines do not hold true for this problem, hence the side lengths couldn't be correct.
How to determine the correct student?The correct student for this problem is obtained using the law of sines.
The law of sines states that the ratio between the sine of each angle and the side length opposite to this angle has to be equal for all the angles in the problem.
Hence the proportional relationship that must be true for the triangle in this problem is given as follows:
[tex]\frac{\sin{90^\circ}}{10} = \frac{\sin{30^\circ}}{5\sqrt{3}} = \frac{\sin{60^\circ}}{5}[/tex]
The sine values are given as follows:
sin(90º) = 1.sin(30º) = 0.5.sin(60º) = 0.866.Hence the ratios are given as follows:
sin(90º)/10 = 0.1.sin(30º)/(5 x square root of 3) = 0.0577sin(60º)/5 = 0.173.Different ratios, hence Rika is correct.
Missing InformationThe triangle is given by the image presented at the end of the answer.

Create and solve by completing the square a quadratic equation with no, 1 , and 2 solutions real solutions. Explain all your steps as if your were teaching a friend.
Answer:
The three quadratic equations are;
x² + 3 = 0
x² + 2·x + 1 = 0
x² + 3·x + 2 = 0
Step-by-step explanation:
1) A quadratic equation with no real solution is one with an imaginary solution such as one with a negative square root
We can write the quadratic equation as follows;
x² + 3 = 0
∴ x = √(-3) = √(-1) ×√3 = i·√(3)
Therefore, the equation f(x) = x² + 3, has no real root at f(x) = 0
2) A quadratic that has 1 real root is of the form;
(x + 1)² = 0
The root of the equation is x = -1 from (x + 1) = ((-1) + 1)² = 0²
Which gives;
(x + 1)² = (x + 1)·(x + 1) = x² + 2·x + 1 = 0
Therefore, the quadratic (x + 1)² = 0 has only one real root
3) A quadratic that has 2 real root is of the form;
(x + 1)·(x + 2) = 0
x² + x + 2·x + 2 = 0
x² + 3·x + 2 = 0
Therefore, the three quadratic equations are;
x² + 3 = 0
x² + 2·x + 1 = 0
x² + 3·x + 2 = 0

1. Explain why the equations below do not have the same solution set. (5 points)
|x| = a and |x| = -a
(Hint: Remember that the
definition of absolute value is related to a number's distance from zero.)
Let's say that 'a' is some positive number. Let's pick a = 5.
That means |x| = a turns into |x| = 5
The equation |x| = 5 solves to x = -5 or x = 5.
This is because the values -5 and 5 on the number line are exactly five units away from zero.
In short, a = 5 leads to |x| = a having the two solutions x = -5 or x = 5.
-------------------
Keeping the same value of 'a', the equation |x| = -a turns into |x| = -5
What number on the number line is exactly negative 5 units away from zero? The answer is "no such number exists". Distance is never negative.
Therefore, |x| = -5 has no solutions.
--------------------
So if a = 5, then the first equation |x| = a has two solutions, while |x| = -a has no solutions.
If we made 'a' to be some negative number, then things would flip around. In this case, it would mean |x| = a has no solutions while |x| = -a has two solutions.
The only time both equations would have a solution is when a = 0
We can see that |x| = a becomes |x| = 0, and |x| = -a becomes |x| = -0 or just |x| = 0 which is the exact same thing the first equation turned into. We're dealing with the same equation at this point.
--------------------
If your teacher states "The value of 'a' is nonzero", then the two equations do not have the same solution set. If a = 0, then it leads to x = 0 as the only solution for both equations.
Matthew has been asked to determine the height of a tree. He measured the height from the ground to his eye and found that it was 5 feet. He used a protractor to measure the angle between the horizontal and his line of sight to the top of the tree. He found that angle to measure 70 degrees He also determined his distance from the tree and found that it measured 12 fect. Use the information to determine the height of the tree .
Answer:
Height of the tree is [tex]37.88[/tex] feet
Step-by-step explanation:
The height of the tree is equal to the sum of distance from ground level to eye level and distance between eye level to the top level of the tree.
Height of the tree [tex]= 5 + X[/tex]
[tex]tan \Theta =[/tex] Perpendicular / Base
[tex]tan\Theta = \frac{X}{12} \\X = 12 * tan70\\X= 12 * 2.74\\X = 32.88[/tex]
Total height of tree [tex]= 5 + X = 5 + 32.88 = 37.88[/tex] feet
