From (? , 6) , x = ? , y = 6
2x - 7y = 0
2x - 7*6 = 0
2x - 42 = 0
2x = 42
x = 42/2
x = 21
The other half of the coordinate is 21
The angles ∠ABC and ∠CBE together should equal 180º.
∠ABC is 155º.
180 - 155 = 25
So, ∠CBE = 25º.
Hope this helps!
Answer:
Below
Step-by-step explanation:
You can use it if you added a hight.
When you a hight you are creating a right triangle. If not you cannot use directly
Answer:
x = -3 and x = 4
Step-by-step explanation:
x-intercept means where the equation touches the x-axis.
At x-axis line, value of y will be 0.
So, y = -2(x+3)(x-4)
becomes 0 = -2(x+3)(x-4)
Now,
x + 3 = 0
x = -3
x - 4 = 0
x = 4
