Answer:x=-1/6,y=0
Step-by-step explanation:
6x-y=-1....(1)
6x+y=-1...(2)
From (2) make y the subject of formula
Y=-1-6x...(3)
Substitute (3)in (1)
6x-(-1-6x)=-1
6x+1+6x=-1
Collect like terms
6x+6x=-1-1
12x=-2
X=-1/6...(4)
Substitute (4) in (3)
Y=-1-6(-1/6)
Y=-1+1
Y=0
Therefore,x=-1/6
Y=0
220= 45*x. I hope you are satisfied with my answer.
Answer:
40
Step-by-step explanation:
1.Kknow the following information;
Remember, the sum of degrees of angles in a triangle is 180.
So say if a traingle contained;
<1, <2, <3,
Then:
<1 + <2 + <3 = 180
2. State the given, and set up an equation;
In this case, it is given that;
<1 = 115
<2 = 25
Therefore, set up the equation;
115 + 25 + <3 = 180
3. Solve the equation;
115 + 25 + <3 = 180
Simplify,
140 + <3 = 180
Inverse operations,
140 + <3 = 180
-140 -140
<3 = 40
