Answer:
x = 25
Step-by-step explanation:
In any triangle, the sum of all 3 angles is ALWAYS 180 degrees. So we can make this into an equation.
4x + 2x+ 10 + x - 5 = 180
Now we combine the like terms.
7x + 5 = 180
Subtract 5 from both sides.
7x = 175
Now divide by 7 on both sides.
x = 25

Answer:
x = 114
Step-by-step explanation:
180 - 105 = 75
39 + 75 = x
x = 114
Step-by-step explanation:
Substituting y in the first equation
At x = 1.17
At x = -1.17
The intersection points are (1.17, 5.85k) and (-1.17, -5.85k)
The graph would intersect regardless of what value k is.
