AB is a diameter. 48° B A What is the measure of BC? 180° 84 42° 96°​
elena-14-01-66 [18.8K]

Answer:

84°

Step-by-step explanation:

The central angle of a circle is twice any inscribed angle subtended by the same arc.

because AB is a diameter, we also know that the triangle angle at C is 90° (all the inscribed triangles with their baseline being a diameter are right-angled).

as always, the sum of all angles in a triangle is 180°.

so, we know the triangle angle at A is

180 - 90 - 48 = 42°.

this is also the inscribed angle of the arc BC.

the central angle for arc BC (that is what is requested here) is then twice that angle : 2×42 = 84°

What is the domain of f/g, given f(x)=x+8 and g(x)=x-3?
Mademuasel [1]
ANSWER
( -  \infty ,3 ) \cup (3, \infty )


EXPLANATION

The given functions are
f(x) =   x + 8

and

g(x) = x - 3

The function,

\frac{f}{g}  =  \frac{f(x)}{g(x)}


This implies that,

\frac{f}{g}  =  \frac{x + 8}{x - 3}

The domain of this rational function refers to all values of x for which

\frac{f}{g}  =  \frac{x + 8}{x - 3}
is defined.


This function is defined if the denominator
x  - 3\ne0


x \ne3


In interval form, we write this as,

( -  \infty ,3 ) \cup (3, \infty )


The correct answer is C.
