vertex = (3,- 5 )
given a quadratic in standard form : y = ax² + bx + c ( a ≠ 0 ), then
the x-coordinate of the vertex is
= - 
y = x² - 6x + 4 is in standard form
with a = 1, b = - 6 and c = 4, hence
= -
= 3
substitute this value into the equation for y- coordinate
y = 3² - 6(3) + 4 = 9 - 18 + 4 = - 5
vertex = (3, - 5 ) → second table
I'm not good at math but I think is 3f because you'll be multiplying f(unknown #) by 3 so f(x) would be 3f
Those are vertical angles,so they are equal
150=5m
m=150/5
m=30
Answer:

Step-by-step explanation:
Recall the mnemonics SOH CAH TOA.
SOH means the Sine ratio is Opposite over Hypotenuse.
This implies that;

The side opposite to angle A is 4cm and the hypotenuse is 5cm.
