Answer:it is b
Step-by-step explanation:
The measurement of angle b is equal to 100
y = x² + 6x + 5
Use the formula: -b/2a
a = 1
b = 6
- 6 / 2
= -3
The x-coordinate of the vertex is -3
Plug the x value back into the original equation to find the y-coordinate of the vertex
y = (-3)² + 6(-3) + 5
y = -4
<h3>Answer: (-3,-4)</h3>
