I dont think so because an acute angle is always lower than 90 so .. i dnt think even two will add up more than 90
I am pretty sure that it's

<h2>We can obtain the other two factors by dividing 858 by 11 and 858 by 13. Thus the other two factors are 78 and 66</h2>
Hope it helps
Since is arithmetic, it's given recursively by
where is a fixed number and is the starting term in the sequence. We have
and so on, so that
We're told that , so
and
so that
Then the first term in the sequence is :
and the sequence has general formula
The first negative term occurs for
The first negative term in the sequence is .
Answer:
y ≥ 6.25
Step-by-step explanation:
f(x)=4x²+2x-6
positive (4) leading coefficient, curve is left up and right up
x coordinate of vertex: x = - b/2a = - 2/2*4 = - 1/4 (-0.25)
y = 4*(-1/4)² + 2*(-1/4) - 6 = -6 1/4 (-6.25) ... extreme
range: y ≥ - 6.25 [-6.25,∞)
