Answer:
128degrees
Step-by-step explanation:
Note that the given triangle ABC is an isosceles triangle with base angles equal, hence;
m∠BAC = m∠BCA
7x+1 = 5x+9
7x - 5x = 9-1
2x = 8
x = 8/2
x = 4
m∠BAC = 5x+6
m∠BAC = 5(4)+6
m∠BAC = 26 degrees
The vertex angle = 180 - (26+26)
The vertex angle = 180 - 52
The vertex angle = 128degrees
I cannot help you with the exact answer, but i can make the solution easier
Get graphs (standard X,Y graphs) and start placein the numbers in the following format (x,y) If they are negative, it will be placed to the left of the graph, if positive to the right of the graph
