There are many steps to find the coordinates of the vertices of triangle ABC.
The slope formula is y2 - y1 / x2 - x1
There would be three equation associated with this problem.
The first equation can be found by taking the x and y's from A and B
First Equation: 2 - 3 / 1 - (-1)
Answer: -.5
The second equation can be found by taking the x and y's from B and C
Second Equation: -1 - 2 / -3 - 1
Answer: 12
The third equation can be found by taking the x and y's from C and A
Third Equation: 3 - (-1) / -1 - (-3)
Answer: 2
These are not equal measurements so, it isn't right angle.
Answer:
166°
Step-by-step explanation:
Supplementary angles have a sum of 180 degrees
That being said, we can find the measure of the missing angle by subtracting the measure of the given angle by 180
(the giving angle having a measure of 14°)
so missing angle = 180 - 14
180 - 14 = 166
Hence, the measure of the second angle 166°
Those lines stand for the absolute value, or how far away it is from zero.
If you draw a number line from -3 to 3, and plot the points x = 2 and x = -2, what similarities do you see?
Although one is two units to the right of 0 and one is two units to the left of 0, both x = 2 and x = -2 are two units away from zero. Therefore, the absolute value of both 2 and -2 is 2.
Y= 12 - x
27 + 3( 12 - x ) = 2x
