Angle D = ABC arc / 2

x + 100 = ABC arc / 2

ABC arc = 2 × ( x + 100 )

ABC arc = 2x + 200 ( ♡ )

_________________________________

Angle B = ADC arc / 2

3x = ADC arc / 2

ADC arc = 2 × 3x

ADC arc = 6x ( ☆ )

_________________________________

ABC arc + ADC arc = 360

( ♡ ) , ( ☆ ) :

( 2x + 200 ) + ( 6x ) = 360

8x + 200 = 360

8x = 360 - 200

8x = 160

x = 160/8

x = 20

____________________________

Thus :

Angle A = 5(20) - 3 = 97 degrees

Angle B = 3(20) = 60 degrees

Angle D = 20 + 100 = 120 degrees

____________________________

Sum of the interior angles of any four-sides figures are equal 360 degrees ,

Thus :

Angle A+Angle B+Angle C+Angle D = 360

97 + 60 + Angle C + 120 = 360

Angle C + 120 + 157 = 360

Angle C + 277 = 360

Angle C = 360 - 270 - 7

Angle C = 90 - 7

Angle C = 83 degrees

A circular jogging track forms the edge of a circular lake that has a diameter of 2 miles. Johanna walked once around the track
Anna [14]

Answer:

C. 2.0 < t < 2.5

Step-by-step explanation:

Diameter of track (D) = 2 miles, Average rate (A) = 3 miles per hour

A = distance/ time

time (t) = distance/A

distance around the track (circumference) = πD = 3.142 × 2 miles = 6.284 miles

t = 6.284miles/3miles/hour = 2.1 hour

Therefore, 2.0 < t < 2.5

B V (D ٨ M)

Step-by-step explanation:

Given :

B : Applicant present a birth certificate

D: Applicant presents a drivers license

M applicant presents a marriage license

1.)

This means that any one of the three must be presented :

Birth certificate OR Driver's license OR Marriage certificate

B v D v M

2.)

This means any two combination of the three certificates :

(birth certificate and marriage certificate) OR (birth certificate and driver's license) OR (marriage certificate and driver's license)

(B ٨ M) V (B ٨ D) V (M ٨ D)

3.)

That is birth certificate alone will suffice or a driver's incense and a marriage certificate

B V (D ٨ M)

What are evidence that the himalayas mountains are still rising​
xeze [42]

Answer:

The Himalayas are still rising by more than 1 cm per year as India continues to move northwards into Asia, which explains the occurrence of shallow focus earthquakes in the region today. However the forces of weathering and erosion are lowering the Himalayas at about the same rate.

1-1 Relations and Functions The following list details the numbers of tickets sold for a talent show: grade 9: 22; grade 10: 32;
zlopas [31]

Answer:

Domain = \{9, 10, 11, 12\}

Range = \{22, 32, 41, 30\}

Step-by-step explanation:

Given

Grade 9: 22

Grade 10: 32

Grade 11: 41

Grade 12: 30

Required

Determine the domain and the range

The domain and range of a function is represented as thus (x,y)

From the given parameters;

(x,y) = (Grade\ 9, 22), (Grade\ 10, 32) (Grade\ 11, 41), (Grade\ 12, 30)

Remove "Grade" to represent as only digits

(x,y) = (9, 22), (10, 32), (11, 41), (12, 30)

Split to x and y values:

<em>Where x = domain and y = range</em>

Domain = \{9, 10, 11, 12\}

Range = \{22, 32, 41, 30\}

<em>So, from the list of given options; option C answers the question.</em>
