$(\stackrel{x_1}{2}~,~\stackrel{y_1}{4})\hspace{10em} \stackrel{slope}{m} ~=~ -3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{4}=\stackrel{m}{-3}(x-\stackrel{x_1}{2}) \\\\\\ y-4=-3x+6\implies y=-3x+10$

Quadrilateral ABCD is a parallelogram. Determine the measure of Angle A

Lunna [17]

Answer:

$\huge\boxed{\text{(A)}\ 96 \textdegree}$

Step-by-step explanation:

A parallelogram has two pairs of identical angles.

The identical angles will be directly opposite from each other.

This means that:

Angle C = Angle A
Angle D = Angle B

Therefore, we can say that Angle A is 3x degrees and Angle B is x+52 degrees.

It's also important to note that all angles in a quadrilateral add up to 360°.

Since we know the measure of each angle, we can add up the expressions for each and find x.

$3x + 3x + (x+52) + (x+52) = 360$

Let's simplify this equation.

$6x+(x+52)+(x+52)=360$
$8x+104=360$

$8x=256$

$x=32$

Now that we know the value of x, let's use it to find the measure of Angle A.

We already proved earlier that Angle C is equivalent to Angle A. Since we know the expression for Angle C (3x) it'll be the same for angle A.

$3(32)=96$

So A is 96°

Hope this helped!

What is the velocity of an object dropped from a height of 180 m when it hits the ground?

Helen [10]

You can use this formula: vf^2=0+2(9.8)(M)
solve it out like so:
vf^2=0+2(9.8)(180)
vf^2=2(1764)
vf^2=3528
now, square both sides to cancel out the power of 2. you are left with:
about 59.4 m/s
