Answer:
x= 110°
Step-by-step explanation:
if you continue drawing the top purple line you will have a triangle with three angles
70° ; is given
180-140= 40°; is the same angle as the supplement angle of 140° (complementary angles are congruent)
180-70-40 = 70°; because sum of angles in a triangle is 180°
So angle x= 180 -70 = 110 because are a linear pair
Answer:
x= 1/2y + 3/2z
Step-by-step explanation:
1/3 (2x-y) =2
multiply 1/3 into the ( )
2/3x -1/3y =2
bring y to the right side by subtrcting
2/3x =1/3y + 2
multiply by the reciprocal of 2/3, which is 3/2
x=3/6y+3/2z
SIMPLIFY!
x=1/2y+3/2z
X=x-9.
Subtract x from both sides of the equation
0=-9
Because this is false, there are 0 solutions.
Final answer: A
It’s the first one, so you’re correct
x=50 and y=10
because of vertical angles: 3y=x-20
and we also have 3y+5x-100=180 , if we simplify we get 3y=280-5x
we can combine the two equations and get x-20=280-5x and when we solve we get x=50 degrees
then we can plug that into the first equation and get 3y=30, and y=10 degrees
