The hardest part of this would be finding the length of that arc. Though, since it's a quarter circle, it makes our job a whole lot easier.

The circumference of a circle is 2πr, therefore, a quarter circumference of a circle would be (2<span>πr) / 4.
</span>
Therefore, the length of that arc would be (2 * 3.14<span> * 8) / 4 = 12.56
</span>

With this figure, we can just add up the rest of the perimeter.

12.56 + 8 (circle radius) + 10 + 10 (two rectangle heights) + 17 (rectangle length) + 9 (rectangle length minus radius, for the top-right part of the rectangle), giving us an answer of 66.56cm

To prove that ΔAED ˜ ΔACB by SAS, Jose shows that StartFraction A E Over A C EndFraction = StartFraction A D Over A B EndFractio
stich3 [128]

The other equality which must be stated by Jose is that angles BAC and BAE are congruent and their measures are equal.

<h3>What other congruence statements must Jose state?</h3>

It follows from the task content that Jose is trying to prove the congruence of both triangles by means of the Side-Angle-Side congruence theorem.

It therefore follows that since, Jose has identified that the ratio of corresponding sides are equal as indicated in the task content, the equality which Jose has to state is the angle congruence equality.

Sn=-441 for the series 19 + 15 + 11 ... tn. Determine the value of n.
kramer

Answer:

sn = d/2·n^2 + (a - d/2)·n

sn = (-4)/2·n^2 + (19 - (-4)/2)·n = -441

- 2·n^2 + 21·n = -441

- 2·n^2 + 21·n + 441 = 0

n^2 - 21/2·n - 441/2 = 0

use pq-Formula

n = -10.5 ∨ n = 21

only n = 21 makes sense. So n = 21 is the correct answer.
