Your answer is 120% of 45
Step-by-step explanation:
Start at (-3,9). The increase in x from this point to the midpoint (3,3) is 6. Add 6 to the x-coordinate of (3,3), obtaining 9, which is the x-coordinate of the other endpoint of the line segment.
Next, notice that y decreases by 6 from 9 to 3 as we travel from (-3,9) to (3,3). Decrease y again by 6: 3 less 6 is -3. So the y-coordinate of the other endpoint is -3.
Thus, the coordinates of the other endpoint are (9, -3).
Let's check whether this is correct or not. According to the midpoint formula, e find the x-coordinate of the midpoint by summing up the endpoint x values and dividing this sum by 2: (-3+9)/2 = 3. This agrees with the given midpoint (3,3).
The measure of both angles are 24 and 66 degrees
<h3>Complementary angles</h3>
The sum of two complementary angles is 90 degrees.
If two angles are complementary, then;
m<K + m<L = 90
where x and y are the angles
Given the following parameters
<K = 3x + 3
<L =10x - 4
Substitute the given parameters into the formula
3x + 3 + 10x - 4 = 90
Collect the like terms
3x+10x - 1 = 90
13x = 90 + 1
13x = 91
Divide both sides by 13
13x/13 = 91/13
x = 7
For the angles
<K = 3x + 3
<K = 3(7) + 3
<K = 24 degrees
Similarly;
<L = 90 - <K
<L = 90 - 24
<L = 66 degrees
Hence the measure of both angles are 24 and 66 degrees
