I think that x may equal to -3. Because the sum of a triangle is always 180. 55+54=109 and 180-109=71 and -3+74=71

Instead of = 360 it should be 180

X+183=180
X= -3

X is -3 that does not make the angle negative 3X -3+74 which is 71 for the angle but it is equal to -3
If you add 55+54+71= 180

<em>Hi there!</em>

<h2>The value of \sqrt{x}0.49x^{18} = 0.49x^{\dfrac{37}{2}}</h2>

Step-by-step explanation:

We have,

 \sqrt{x(0.49)}x^{18}

To find, the value of \sqrt{x(0.49)}x^{18} = ?

∴  \sqrt{x(0.49)}x^{18}

= 0.7x^{\dfrac{1}{2}} x^{18}

= 0.7x^{18+\dfrac{1}{2}}

Using the identity,

a^{m}.a^{n}=a^{m+n}

= 0.7x^{\dfrac{36+1}{2}}

= 0.7x^{\dfrac{37}{2}}

Thus, the value of \sqrt{x(0.49)}x^{18} = 0.49x^{\dfrac{37}{2}}

Hello!

<h2>Answer:</h2>

The correct answer is the second option: rotation, then translation, then reflection.

<h2>Explanation:</h2>

Start with the triangle on the left. You rotate A'B'C and you get the top right one. Then, you translate this down. Finally, you reflect it and get A"B"C" (triangle on the bottom right).
