Answer: The area is 15 square units
Step-by-step explanation: It is helpful to sketch the coordinates on a graph to get an idea of what the triangle looks like so you can see which side will be the base, and where to get the height. You will see that AB is the hypotenuse, it is a right triangle, so AC can be the base and BC is the height.
Use the differences in x-values of points C & A to get the length of the base: 2-(-3) is 5
Use the differences in y-values of points B & C to get the height:
4-(-2) = 6
Area = bh/2
A = 5×6/2 = 30/2
A = 15 square unts
Answer:
X = 6

Mean: 11.4
Median: 7
Mode: there isn't one
Mean: 1+5+7+12+32=57 57÷5=11.4
Median: 1, 5, 7, 12, 32. 7 is the middle number.
Mode: there isnt a number that repeats itself.
