True!

<h2>Explanation:</h2>

The Cartesian coordinate system is formed by two perpendicular axes, which are the x-axis and y-axis. In this problem, we are given two lines:

$x=4 \ and \ y=5$

The line $x=4$ is parallel to the y-axis and has an undefined slope.
The line $y=5$ is parallel to the x-axis and has a slope of zero.

Since the x and y-axes are perpendicular, then the lines $x=4 \ and \ y=5$ are also perpendicular.

Answer:

1) ∠A=84°

2) ∠C=20°

Step-by-step explanation:

First, find ∠C:

<em>(I'm assuming the exterior angle of 126° makes a straight line with ∠C)</em>

The angles on a straight line always add up to 180. Therefore:

∠C+126=180

∠C=180-126

∠C=54

Then find ∠B:

We also know that all the angles in a triangle add up to 180. Therefore:

∠A+∠B+∠C=180

∠A+∠B+54=180

∠A+∠B=126

2(∠B)+∠B=126

3(∠B)=126

∠B=42

Now, find ∠A:

∠A=2(∠B)

∠A=2(42)

∠A=84°

First, find ∠B:

<em>(Again, I'm assuming the exterior angle of 100° makes a straight line with ∠B)</em>

The angles on a straight line always add up to 180. Therefore:

∠B+100=180

∠B=180-100

∠B=80

Then find ∠A:

We also know that all the angles in a triangle add up to 180. Therefore:

∠A+∠B+∠C=180

∠A+80+∠C=180

∠A+∠C=100

4(∠C)+∠C=100

5(∠C)=100

∠C=20°

Question 4(Multiple Choice Worth 1 points) (08.01 LC) What are the x-intercepts of the parabola? graph of parabola falling from

gulaghasi [49]

Answer:

(4, 0) and (5, 0)

Step-by-step explanation:

Given

See attachment for graph

Required

The x intercepts

This is the point where $y = 0$

From the graph, we have the following as the x-intercepts:

$(x_1,y_1) = (4,0)$

$(x_2,y_2) = (5,0)$

Because the curve crosses the x-axis at the above points

If the volume of the pyramid is 64 ft³; and the height is 16 ft, what is the base area measured in square feet?

Law Incorporation [45]

The volume of a pyramid would be the base area times the height.
Given the height and volume we can find the base ares by dividing the volume by the height.

64 / 16 = 4

The base area is 4 square feet
