Answer:
x=81
y=99
z= 129
Step-by-step explanation:
the 3 angles of a triangle add to 180 degrees
51 + 48 + x = 180
99 + x = 180
subtract 99 from each side
99 + x -99 = 180 -99
x = 81
x+y = 180 they make a straight line
81+ y = 180
subtract 81 from each side
y = 180-81
y = 99
z+ 51 = 180 they make a straight line
subtract 51 from each side
z+51-51 = 180 -51
z = 129
Answer:
a. Point.
b. Vertex.
c. Line.
d. Line segment.
e. Ray.
Step-by-step explanation:
a. <u>Point</u>: a location, has no dimension. Also, a point doesn't have a size i.e no length, depth, breadth or height.
b. <u>Vertex</u>: is the common endpoint of two segments or rays that form the "corner" of an angle.
c. <u>Line</u>: is an infinite number of points extending in opposite directions that has only one dimension.
d. <u>Line segment</u>: is part of a line that has two endpoints.
e. <u>Ray</u>: is part of a line that has one endpoint and continues in one direction infinitely.
Answer:
6x^2.
Step-by-step explanation:
The first term 6x^2, because 6 is not a perfect square.
I believe the answer is 2.2 but i could be wrong and if so sorry.
