Answer:
9)=95°
10)=120°
Step-by-step explanation:
9) = 10x+5 = -4+11x - vertically opposite
or, 5+4 = 11x-10x
or, x = 9
now
10x+5
= 10*9+5
= 90+5
= 95
9)= 95°
10)= soln
16x-4+31x-4=180-being cointerior
or, 47x-8=180
or, 47x= 188
so, x = 4
now
31x-4
= 31.4-4
=124-4
=120
10)=120°
Answer:
inconsistent
Step-by-step explanation:
The sum of the first and last equations is ...
(2x +3y -z) +(x +3y +z) = (-1) +(12)
3x +6y = 11
Three times the second equation is ...
3(x +2y) = 3(5)
3x +6y = 15
There are no values of x, y, or z that can make both of these equations true. They are inconsistent.
