Answer:
Real number 5
Imaginary number 5i
Complex number 2+5i
Step-by-step explanation:
A real number is that number that can be represented on number line
There is no imaginary part in real number
Example of real number is 5
Imaginary number is that in which there is no real part
Example of imaginary number is 5i
When there is a combination of both real and imaginary part then number is called complex number
Example of complex number is 2+5i
Answer:
Option A
Step-by-step explanation:
The complete question is shown in the attachment.
The sum of angles in a triangle is 180 degrees.
This implies that:

m<A+138=180
m<A=180-138=42
Now we use the sine rule to find AC=b

This implies that:


Answer:
a
Step-by-step explanation:
g(1)=5
f(g(1))=f(5)
f(5)=2
As an improper fraction, it would be -11/4
As a mixed number, it would be
-2 and 3/4
Trigonometry can be used to find angles and sides of simple triangles. If an 18-foot ladder touches a building 14 feet up the wall then the angle can be deduced by trigonometry. In this case, the ladder defines the hypotenuse (H) of the triangle and the wall defines the opposite (O) side of the triangle. Therefore we can use the equation theta=sin^-1(O/H) . This yields an angle of 51 degrees.
