Hi there! The answer is A. x = 12
The angles (taken together) are complementary angles: the sum of the angles is 90 degrees. When we know this, we can set up and solve an equation.
(3x + 6) + 48 = 90
Work out the parenthesis
3x + 6 + 48 = 90
Collect terms
3x + 54 = 90
Subtract 54
3x = 36
Divide by 3
x = 36 / 3 = 12
Therefore, the solution for x, gives x = 12. A is the correct answer.
Answer:
Equation has one real root and two complex roots.
Step-by-step explanation:
The equation
consists of two parts. The left side of this equation can be represented by the function
and the right side can be represented by the function
Graphs of both these functions are shown in the attached diagram.
These graphs have one common point, this means that the equation
has one real solution (approximately, x≈-1.839).
Given equation is cubic, then this equation has three roots. Since only one root is real, then two remaining roots are complex.
For this case we have the following number:

What we must do is rewrite the number as the product of two numbers.
We have then:

From here, we write the number as the multiplication of a whole number and a power of base ten.
We have then:

Where,
: whole number
: power of base 10
Answer:
The distance written as a whole number multiplied by a power of ten is:

Answer:
96 laps
Step-by-step explanation:
2 hours = 2 * 60 = 120 minutes
So now the question would be as given below:
8 laps in 10 minutes so how many laps in 120 minutes.
Since, no. of laps and minutes are in proportion.

Answer:
27 Degree
Step-by-step explanation:
First Draw the graph (If you want)
Tan is what we have to use because TAN = Opposite / Adjacent
TanA=2/4
TanA=1/2
TanA=0.5
Tan^-1 x (0.5)
<A= 26.565...
ROUND TO THE NEAREST DEGREE = 27 Degrees
