Answer:
Replace the y, z, and x values with real numbers .
0 - 3 = -3
5 + 4 = 9
3 + 4 = 7
For area you would times the two sides you have together
10 x 10 = 100
Answer:
The distance of the foot of the ladder to the building is 14 ft.
Step-by-step explanation:
The length of ladder = 20 ft
Angle formed by ladder with level ground, θ = 46
We are required to find out the distance of the foot of the ladder from the building
The above question can be found out by using trigonometric relations as follows;
The adjacent side of the right triangle formed by the ladder the building and the ground is the distance of the foot of the ladder from the building
The hypotenuse side is the length of the ladder = 20 ft
Therefore;
Adjacent side of triangle = Hypotenuse × cosθ
∴ Distance of the foot of the ladder from the building = Hypotenuse × cosθ
Distance of the foot of the ladder from the building = 20 ft × cos(56)
Distance of the foot of the ladder from the building = 13.893 ft
To the nearest foot, the distance of the foot of the ladder to the building = 14 ft.

The diagram is drawn and attached below.
Now, AB is a straight line.
Answer:
D, ininitely many
Step-by-step explanation:
A- incorrect since the lines intersect
B - incorrect since the lines intersect at more than one point
C - incorrect since the lines intersect at more than 2 points
D- correct since the lines intersect at infinitely many points (since they're the same line)
