$1.95 x 18
Each segment on the grid represents 1 unit.
Answer:
The triangle is shown in the below diagram.
Step-by-step explanation:
It is given that each segment on the grid represents 1 unit and point A is a vertex of a right angle triangle.
The height of triangle is 4 units, and the base is 5 units.
Let the coordinates of A be (x,y).
There are many possibilities to draw a right angled triangle having height 4, base 5 and vertex at A.
The height of the triangle is 4 units, so the coordinate of another vertex B is (x,y+4).
The base of the triangle is 5 units, so the coordinate of another vertex C is (x+5,y).
The triangle is shown in the below diagram.
A. 180°+z−w
B. 180°–z−w
C. w−z
D. 180°+w−z
Answer:
A. 180°+z−w
Step-by-step explanation:
We know that x + w = 180 because they are same side exterior angles and a and b are parallel.
z=y because they are alternate interior angles and a and b are parallel.
x + w = 180
Solve for x by subtracting w from each side
x = 180-w
y =z
Lets find x+y
x+y
(180-w) +z
Rewriting
180+z-w
Answer:
A. 180º + z - w
Step-by-step explanation:
x + w = 180, because they are same side exterior angles, and are on opposite sides.
z = y, because if you move z down, then you will see that they overlap.
From x + w = 180, you can get x = 180 - w.
We are trying to find x + y in terms of w and z, so:
x = 180 - w
y = z
With that, you can assemble the expression, 180 - w + z.
If you re-arrange, you will get 180 + z - w.
Therefore, A is the answer.
