Answer:
≈ 11.34 units²
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x + 3.5)² + (y - 2.82)² = 25 ← is in standard form
with r² = 25 ⇒ r = 
= 5
The area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² × 
= π × 5² ×
= π × 25 ×
= 
≈ 11.34 units² ( to the nearest hundredth )

Answer:
$74.67
Step-by-step explanation:
Let p represent the original price. Then the relation is ...
$56 = p - 0.25×p
$56 = 0.75p
$56/0.75 = p ≈ $74.67
The original price was $74.67.

Answer:
Triangles are similar using AAA rule of similarity.
Step-by-step explanation:
Let's take triangle ACD. Where <D =60 degrees. <A =74.9 degrees and let's find <C using angle sum property of a triangle.
Please remember the sum of interior angle of a triangle is 180 degrees.
So, m<D= 180-60-74.9 =45.1 degrees.
Other triangle RST has the two angles as 74.9 degrees and 45.1 degrees.
So, third angle <T= 180-74.9-45.1= 60 degrees.
If we see the angles of a triangle, both has same angle measures.
That's <A= <R
<C= <S
<D= <T
So, the triangles are similar using AAA rule of similarity.
