A right △ABC is inscribed in circle k(O, r). Find the radius of this circle if:

natta225 [31]

We have been given that a right △ABC is inscribed in circle k(O, r).

m∠C = 90°, AC = 18 cm, m∠B = 30°. We are asked to find the radius of the circle.

First of all, we will draw a diagram that represent the given scenario.

We can see from the attached file that AB is diameter of circle O and it a hypotenuse of triangle ABC.

We will use sine to find side AB.

$\text{sin}=\frac{\text{Opposite}}{\text{Hypotenuse}}$

$\text{sin}(30^{\circ})=\frac{AC}{AB}$

$\text{sin}(30^{\circ})=\frac{18}{AB}$

$AB=\frac{18}{\text{sin}(30^{\circ})}$

$AB=\frac{18}{0.5}$

$AB=36$

Wee know that radius is half the diameter, so radius of given circle would be half of the 36 that is $\frac{36}{2}=18$ .

Therefore, the radius of given circle would be 18 cm.

Answer:

$(\frac{5}{2},-\frac{7}{2})$

Step-by-step explanation:

The complete question is

What is the midpoint of the segment shown below?

(1,-1) (4, -6)

we know that

The formula to calculate the midpoint between two points is equal to

$M(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

we have

$(x_1,y_1)=(1,-1)\\(x_2,y_2)=(4,-6)$

substitute the given values

$M(\frac{1+4}{2},\frac{-1-6}{2})$

$M(\frac{5}{2},-\frac{7}{2})$

Answer:

1400 square units

Step-by-step explanation:

The area can be computed by subtracting the areas of the white rectangles at three corners from the overall 60×30 rectangle.

The upper left corner white space is 10×10 = 100 square units.

The upper right and lower left white spaces are 15×10 = 150 square units each.

Then the shaded area is ...

60×30 -100 -2(150) = 1800 -100 -300 = 1400 . . . square units

_____

Alternate solution

You can extend each of the horizontal edges across the figure to divide it into three rectangles. From the top down, these have dimensions and areas of ...

35×10 +60×10 +45×10 = 10(35+60+45) = 10(140) = 1400 . . . square units

Area of a rectangle is the product of length and width.
