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.

Every week malik spends 5 2/15 hours doing his math homework and 2 13/30 hours doing his science homework. Estimate how much mor

ArbitrLikvidat [17]

This is Simple, Just Subtract Time taken by Science homework from time taken by Maths homework..

$= 5 \frac{2}{15} - 2 \frac{13}{30} \\ = \frac{150}{15} - \frac{73}{30} \\ = \frac{300 - 73}{30} \\ = \frac{227}{30} \\ = 7 \frac{17}{30} \: hours \: more.$

Complete the table of values for y = 6 - 2x

Tpy6a [65]

Step-by-step explanation:

a) substitute x values:

6-2(0) = 6

6-2(1) = 4

6-2(2) = 2

6-2(3) = 0

6-2(4) = -2

6-2(5) = -4

b) rewrite equation as y=-2x+6.

this shows a negative slope with a y-intercept of 6.

c) 3=6-2x

-6 -6

-3 = -2x

divide both sided by 2

-3/-2 = x

3/2=x
