⭐️- Remember that slope formula is y=mx+b

1. Know that the m is (-3)
2. 4=(-3)(9)+b
3. 4=(-27)+b
4. b=31
5. y=(-3x)+31
6. y=3x-31*

*whenever it is finding a perpendicular, you switch the signs; when it is finding a parallel, you leave it alone

To copy an angle using only a compass and a straightedge, begin by marking the vertex of the new angle. Then draw a ray from the
podryga [215]

The <em>correct answer</em> is:


Place the point of the compass on the vertex of our original angle. Open the compass to a random width and draw an arc through both legs of the angle. Mark the points of intersection with this arc and the sides of the angle.


Explanation:


In order to copy the angle, we need to have some reference for how wide the angle is.


So far all we have is a ray. To get the reference for the width that we need, we will construct an arc in the original angle such that it intersects each side of the angle.


We will then set the compass width to these points of intersection. This will be how we set the width of the new angle.

Question 3
zlopas [31]

Answer:

Area = 19.05 feet squared

Step-by-step explanation:

By applying sine rule in ΔABC,

sin(∠CAB) = \frac{\text{Opposite side }}{\text{Hypotenuse}}

sin(60°) = \frac{BC}{AC}

\frac{\sqrt{3}}{2}=\frac{BC}{4}

BC = 2√3

Area of a parallelogram is given by the formula,

Area = Base × Height

        = 5.5 × 2√3

        = 11√3

        = 19.05 ft²

Therefore, answer is Area = 19.05 ft squared.
