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° .
_________________________________________

Please help i don’t know how to do this
Leviafan [203]
35 Degrees. This is because the a straight line is 180 degrees. Knowing this, 180-100= 80. 80+65= 145. 180-145=35 which is the missing angle.

8y-10=6y-2 help me please I don't get this
murzikaleks [220]
8y-10=6y-2 

8y-10=6y-2:y  | Solve \ for \ y| 

8y=6y-2+10
 
  |Add \ 10 \ to \ both \ sides| 


8y=6y+8
 
 


8y-6y=8
 
  |Subtract \ 6y \ from \ both \ sides|

2y=8 

y=8/2   |Divide \ both  \ sides \ by \ 2|

y=4 

\star \ Hence \ solved
