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.
Wee know that radius is half the diameter, so radius of given circle would be half of the 36 that is 
.
Therefore, the radius of given circle would be 18 cm.
Answer:
27 females are in the class
Step-by-step explanation:
Spilt 30 into 10 (30 divided by 10) and then you get 3. The number of males in the class is 3. Now subtract 30 from 3 and you get 27. Therefore, there are 27 females in the class.
Answer:
The y-coordinates of the solutions to the system and the zeroes of the equation are not equal.
Step-by-step explanation:
Answer:
A -(27x + 7)
B -(15x + 8 )
C -9(2x + 1 )
Step-by-step explanation:
-1/2 (30x + 16) = -15x-8
