Answer:

y=63

Step-by-step explanation:

Start off by adding 13 to both sides:

1/3y-13=8

+13 +13

Now you have this:

1/3y=21

Now multiply each side by 3/1 (3) to get your answer:

(3) 1/3y=21 (3)

Y=63

Check your answer:

63/3=21 21-13=8

I hope this helps, and have a great day! <3 :)

Find the length of midsegment YZ in trapezoid ABCD when A(-5,-6) B(-6,-2) C(-4,0) and D(3,2)

Luda [366]

Answer:

Option C

Step-by-step explanation:

Since, Y and Z are the midpoints of sides AB and CD of the given trapezoid.

Segment YZ will the midsegment of trapezoid ABCD.

By the theorem of midsegment,

m(YZ) = $\frac{1}{2}(AD+BC)$

By using expression for the length of a segment between two points,

Length of a segment = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Distance between two points A(-5, -6) and D(3, 2),

AD = $\sqrt{(3+5)^2+(2+6)^2}$

AD = $\sqrt{64+64}$

AD = $\sqrt{128}$

AD = $8\sqrt{2}$

Distance between B(-6, -2) and C(-4, 0)

BC = $\sqrt{(-6+4)^2+(-2-0)^2}$

BC = $\sqrt{8}$

BC = $2\sqrt{2}$

Therefore, m(YZ) = $\frac{1}{2}(8\sqrt{2}+2\sqrt{2})$

= $\frac{1}{2} (10\sqrt{2})$

= $5\sqrt{2}$

Option C will be the answer.

Find the value of k. the diagram is not to scale

Nesterboy [21]

Given:
∠SRT ≅ ∠STR,
m∠SRT = 20,
m∠STU = 4x

Since ∠SRT ≅ ∠STR, then m∠STR = 20.

m∠STR + m∠STU = 180°
20 + 4x = 180
4x = 180 - 20
4x = 160
4x/4 = 160/4
x = 40

The value of x is 40.

I hope this is what you're looking for.

Answer:

An author can control the pacing of a story by changing the sentence structure or how quickly events unfold in a story. Pacing is a tool used in literature intended to control the speed and rhythm at which a story is told and the readers are pulled through the events.
