Answer:

Step-by-step explanation:

Equation of a circle is

(x-h)^{2} +(y-k)^{2} =r^{2} where (h,k) is the center and r is radius

#5 Radius 2, Center (4,-3)

(x-4)^{2} +(y+3)^{2} =4

#6 Radius 7, Center (-1,10)

(x+1)^{2} +(y-10)^{2} =49

What are the missing sides in the triangle written as integers or as decimals rounded to the
Alecsey [184]

The value of x is 12.7 and the value of y is 9. The correct option is the third option x = 12.7; y = 9

<h3>Trigonometry </h3>

From the question, we are to determine the values of the missing sides

From the diagram,

Opposite = 9

Adjacent = y

Hypotenuse = x

Included angle = 45°

Using SOH CAH TOA, we can write that

tan 45^\circ= \frac{9}{y}

1 = \frac{9}{y}

∴ y = 9

Since the triangle is a right triangle, we can write that

x² = y² + 9² (<em>Pythagorean theorem</em>)

x² = 9² + 9²

x² = 81 + 81

x² = 162

x = √162

x = 12.7

Hence, the value of x is 12.7 and the value of y is 9. The correct option is the third option x = 12.7; y = 9

In the diagram of PARALLELOGRAM ABCD, segment BE is perpendicular to segment CED, segment DF is perpendicular to BFC and segment
tiny-mole [99]

Answer:

In parallelogram ABCD

FD is perpendicular to BC

BE is perpendicular to CD

Consider triangle BEC and triangle DFC

FC = EC (Given)

Angle BEC = Angle DFC (=90°)

Angle BCE = Angle DCF (common)

Therefore triangle BEC is congruent to triangle DFC (AAS congruency)

DF = BE (CPCT)

Since the altitudes are equal their bases will also be equal

Therefore BC = DC

Therefore BC = DC = AD = AB

Therefore ABCD is a rhombus

Hope this helps!
