Answer:

15 inches

Step-by-step explanation:

The ratio of sides in 30º-60º-90º triangle is:

a : b : c = 1 : √3 : 2

If a is 5√3, the length of b is:

b = a√3 = 5√3 *√3 = 5*3 = 15

The circumference of a circle is 62.8 centimeters. What is the circle's radius?

Kobotan [32]

Hello!

To solve this exercise, we must use the formula below:

$\mathrm{C=2\cdot\pi\cdot r}$

C = 62.8cm
π = 3.14
r = ?

Knowing these values, let's replace them in the formula to obtain r:

$\mathrm{62.8=2\cdot\ 3.14\cdot r}\\\mathrm{62.8=6.28r}\\\mathrm{6.28r=62.8}\\\\\mathrm{r=\dfrac{62.8}{6.28}}\\\\\boxed{\mathrm{r=10}}$

So, the radius of this circle is 10cm.

Hope this helps!

What is the slope of the line? a. –2 b. –1/2 c. 1/2 d. 2

mojhsa [17]

Hey!

The formula for slope is: $\frac {y_2-y_1} {x_2-x_1}$ or: $\frac{change\ in\ x}{change\ in\ y}$

y₂ = 2

y₁ = 3

x₂ = 4

x₁ = 2

That gives you:

$\frac{2-3}{4-2} = \frac{-1}{2}$

That means your answer is B

$\framebox{Answer = B.}$
