Geometry! What describes line FI?

1 answer:

3 0

Defining "bisect" is a good first step in figuring this one out; when we say an angle or a line is being "bisected," we mean that it's being split in half, into two equal angles/line segments. Here, the line segment FI seems to be dividing the line segment EG in half, as evidenced by the congruent line segments EF and FG. Notice too that the angle the line forms, ∠EFI, is right. What keyword in those four options has something to do with right angles?

I need help with the photo below.

Here, 30/360 * 2πr = 10
1/12 * 2 * 3.14 * r = 10
r = 10*12 / 6.28
r = 19.11

Now, Area = 1/12 * 3.14 * (19.11)²
= 3.14/12 * 365.16
= 95.5 Ft²

In short, Your Answer would be Option C

Hope this helps!

Find the equation of the line that passes through the given points. (1, 4.5) and (3, 6)

Zanzabum

Answer:

y=0.75x+3.75

Step-by-step explanation:

The slope is

$\frac{6 - 4.5}{3 - 1} = \frac{3}{4}$

Substituting into point-slope form,

y - 6 = 0.75(x - 3)

y - 6 = 0.75x - 2.25

y = 0.75x + 3.75
