A, B and C are collinear and B is in the middle.
so we have AB + BC =AC
6x +x-5= 23
7x -5=23
adding 5 to both sides
7x=23+5
7x =28
dividing both sides by 7
we get x=28/7 =4
So answer is x=4
Answer:
x = 74°
Step-by-step explanation:
opposite sides are congruent causing it to have the same angle
Answer: {x,y} = {2,-4}
[1] x - y = 6
[2] 2x + y = 0
Answer: 4/25
75
Step-by-step explanation: Simple. 50/2=25, 25+50=75.
