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

The zeros of the quadratic expression are 1/4 and -9/5
Given the quadratic function:
To get the zeros of the function, we will equate the function to zero to have:
Factorize the function;
16x^2 + 36x - 4x - 9 = 0
4x (4x+9) - 1(4x + 9) = 0
(4x - 1) (4x + 9) = 0
4x - 1 = 0 and 4x + 9 = 0
4x = 1 and 4x = -9
x = 1/4 and -9/5
Hence the zeros of the quadratic expression are 1/4 and -9/5
