If angle 1 and angle 7 are vertical angles and angle 1 and angle 2 are supplementary adjacent and the measure of angle 2 is 123
JulsSmile [24]
Answer:  m∡7 = 57° .
_________________________________

Explanation:
____________________
 m∡7 = m∡1 ;  SInce  these angles are vertical; and vertical angles are congruent.

m∡1 + m∡2 = 180 ; since these angles are supplementary; and by                                            definition; supplementary angles "add up" to 180.

Given: m∡2 = 123 ;  

m∡1 + 123 = 180 ;

Since m∡1 = m∡7 ; and we wish to find: "m∡7" ;  we can rewrite as:
_______________________________
m∡7 + 123 = 180 ; solve for "m∡7" ;
_______________________________
Subtract "123" from EACH SIDE of the equation:
_________________________________________
  m∡7 + 123 - 123 = 180 - 123 ;
_________________________________________
  m∡7 = 57° .

Need help please its my last question
Nesterboy [21]

Given:

Radius of circle = 12 units

Area of sector = 24π sq. units.

Central angle = x

To find:

The value of x.

Solution:

We have,

r=12

A=24\pi

\theta = x

We know that, area of a sector is

A=\dfrac{\theta }{360^\circ}\pi r^2

Where, \theta is central angle, r is radius.

24\pi=\dfrac{x}{360^\circ}\pi (12)^2

24\pi=\dfrac{x}{360^\circ}\pi (144)

\dfrac{24\pi}{144\pi}=\dfrac{x}{360^\circ}

\dfrac{1}{6}=\dfrac{x}{360^\circ}

Multiply both sides by 360 degrees.

\dfrac{1}{6}\times 360^\circ=x

60^\circ=x

The value of x is 60 degrees.

Therefore, the correct option is A.
