Hey can anyone help with this question?

schepotkina [342]

(AB)^2 + (2 m)^2 = (8 m)^2, or

(AB)^2 + 4 m^2 = 64 m^2, or (AB)^2 = 60 m^2.

Taking the square root of both sides, (length of AB) = + 2sqrt(15) (answer)

]solomon needs to justify the formula for the arc length of a sector. which expression best completes this argument? the circumf

Anna35 [415]

Answer:

$\frac{2 \pi r}{\frac{360^{\circ}}{n^{\circ}}}$ best completes this argument

Step-by-step explanation:

Circumference of circle = $\pi \cdot d$

Where d is the diameter of circle

We are given that if equally sized central angles, each with a measure of n°, are drawn, the number of sectors that are formed will be equal to $\frac{360^{\circ}}{n^{\circ}}$

So, Number of sectors = $\frac{360^{\circ}}{n^{\circ}}$

The arc length of each sector is the circumference divided by the number of sectors

$\Rightarrow \frac{\pi \cdot d}{\frac{360^{\circ}}{n^{\circ}}}$

Diameter d = 2r (r = radius)

$\Rightarrow \frac{2 \pi r}{\frac{360^{\circ}}{n^{\circ}}}$

Option b is true

Hence $\frac{2 \pi r}{\frac{360^{\circ}}{n^{\circ}}}$ best completes this argument

19-8c>3 what does it equal to

nadya68 [22]

Rearrange 19 × 8 × c-(3)>0

Pull out the like terms (factors) 16- 8c = -8 × (c-2)

Divide each side by. -8

Add 2 to each of the sides

So, C<2 would be your result
