What is the value of x? The figure contains 2 lines that intersect to form what looks like an x. Two of the 4 angles in the x ar

Gnom [1K]

Answer:

$x=38.5^\circ$

Step-by-step explanation:

Given that the left angle = $(3x-3)^\circ$

The right angle across from it $= 6(x-10)^\circ$

The other two angles are x and x.

We know that the sum of angles at a point equals 360 degrees.

Therefore,

$(3x-3)^\circ+6(x-10)^\circ+x+x=360^\circ\\3x-3+6x-60+2x=360\\11x-63=360\\11x=360+63\\11x=423\\x=38.5^\circ$

The value of x is approximately 38.5 degrees.

I know that real numbers consist of the natural or counting numbers, whole numbers, integers, rational numbers and irrational nu

ra1l [238]

The imaginary unit $i$ belongs to the set of complex numbers, denoted by $\mathbb C$ . These numbers take the form $a+bi$ , where $a,b$ are any real numbers.

The set of real numbers, $\mathbb R$ , is a subset of $\mathbb C$ , where each number in $\mathbb R$ can be obtained by taking $b=0$ and letting $a$ be any real number.

But any number in $\mathbb C$ with non-zero imaginary part is not a real number. This includes $i$ .

"is it possible that i can use an imaginary number for a real number"

I'm not sure what you mean by this part of your question. It is possible to represent any real number as a complex number, but not a purely imaginary one. All real numbers are complex, but not all complex numbers are real. For example, 2 is real and complex because $2=2+0i$ .

There are some operations that you can carry out on purely imaginary numbers to get a purely real number. A famous example is raising $i$ to the $i$ -th power. Since $i=e^{i\pi/2}$ , we have

$i^i=\left(e^{i\pi/2}\right)^i=e^{i^2\pi/2}=e^{-\pi/2}\approx0.2079$

Vedmedyk [2.9K]

Complementary angles add up to 90 degrees. Supplementary angles add up to 180 degrees, so no.
