(2x - 5)° + 45° = 180°

2x° + (-5 + 45)° = 180°

2x° + 40° = 180°

2x° = 180° - 40°

2x° = 140°

x° = 140 ÷ 2

x° = <u>7</u><u>0</u><u>°</u>

So, the value of x is 70°

Roots are the x-intercepts that help find the axis of symmetry (add the two roots together and divide the result by 2 to get the axis of symmetry)


To find the vertex, simply imput the axis of symmetry into the given equation.


And that’s about it.
