Answer:
angle 1 is 42
angle 2 is 138
angle 3 is also 42
Step-by-step explanation:
for angle 1, I don't remember what the exact rule was but basically since they are opposite of each other they are equal
for angle 2 all you have to do is subtract 42 from 180 because line n is at an angle of 180 and line m simply splits it into two pieces
for angle 3, I dont remember what the exact rule is or hot to explain it well but it is also 42
Answer:
You divide the area by the number you already have.
Step-by-step explanation:
I think the answer is true.
Answer:
Use the distance formula to find the length of each side, and then add the lengths.
Step-by-step explanation:
We are given the vertices of a quadrilateral in the coordinate plane.
We have to find the perimeter of the figure.
For doing so, we have to find the length of all the sides of a quadrilateral
The length of a line segment joining points (x1,y1) and (x2,y2) is given by the distance formula: 
after finding length of all the sides, we add the length of each side to get the perimeter.
Hence, the correct option is:
Use the distance formula to find the length of each side, and then add the lengths.
