Answer:
Third choice, m<EGB plus m<BGC!
Step-by-step explanation:
You know that m<BGC is 90 degrees. A straight line is 180 degrees. Line AGC is 180 degrees. Therefore, m<of EBG is 90 degrees. Hope this helps!
Hello from MrBillDoesMath!
Answer: Using the diagram provided the question can not be answered.
Discussion:
The 3 angles of a triangle add up to 180. From the diagram
73 + ( 6x + 4) + ( 8y -7) = 180
This equation has two variables, x and y, and we can't solve it as such. BUT if the third angle was intended to be (8x -7), an assumption totally, then
73 + ( 6x + 4 ) + ( 8x -7) = 180 or
73 + (6x + 8x) + (4 -7) = 180 or
73 + 14x -3 = 180 or
14x + 70 = 180 or
14x = 180 -70 = 110
x = 110/14 = 55/7
Thank you,

If you simplify this into the general form of an equation for an x^2 parabola, what you get is y = - .25x^2. Because there is no up or down movement, nor is there any side to side movement, this parabola is still sitting at the origin. The - out front turns it upside down, and the value of 1/4 makes it open up wider that its parent function y = x^2. So the axis of symmetry is x = 0 which is actually the equation for the line of symmetry. The axis of symmetry is the y axis because the function opens up evenly on each side of the y axis.
